Wheat variety of pests becoming heavy attention to the timely prevention and treatment

As temperatures steady rise, wheat variety of pests, especially to accelerate the development of stripe rust, heavier, prevention and control work has entered a critical period. According to the site and local surveys, wheat stripe rust in mid-December last year, has begun to see in late disease, see the disease early time, degree of emphasis are no past two decades; currently Shen Tan Tan Xiang Zhang Wan Fang The earliest point Kawamura see disease has spread to the whole field and the surrounding fields, more than 60% disease Tian, ​​ill fields diseased leaves rate of 7 - 24%, the local strain rate of 100% (see below photo); recent The temperature and humidity are on stripe rust expansion and spread very favorable, and has begun to enter Sheng epidemic; back sprayers Part Catcher spider, sheath blight, powdery mildew, also has heavier occurred among the one hundred local spider insects of up to 6,000 or more, the amount of 50 single leaf insects more than the amount of 120 insects per plant or more. Therefore, improving the current wheat pest control work is to ensure that the harvest of wheat yield important part localities must seize, grasp, prevention and treatment. Now the main pest control techniques as outlined below:
A, control time
1, wheat stripe rust, powdery mildew: In late March, the first pass drug must be administered, the incidence of heavy plots, in April, the middle and then spraying 1 - 2 times.
2, wheat sheath blight: strain rate of more than 10% of the plots should be timely drug prevention and treatment, the incidence of severe plots interval 7-10 days and then spraying 1 - 2 times.
3, wheat spider: the amount of one hundred insects over 500 plots to drug prevention and treatment.

Second, the control methods
1, wheat stripe rust, powdery mildew: mu 15% triadimefon WP 100 g (2 2), or 20% triadimefon EC 60 ml, 12.5% ​​diniconazole (Wo fruit Lee) 60-80 g , manual sprayers watered 60 kg, 15 kg watered motorized sprayer spray.
2, wheat sheath blight: mu 5,000,000 units Jinggangmycin 50 grams, manual sprayers watered 50 kg, 15 kg watered motorized farm sprayer spray.
3, wheat spider: mu 73% propargite EC 1500 times, or 1.8% abamectin 3000 times, 20% off Hartley 1800 times, 50 kg sprayer watered, watered 15 motorized sprayer kg, jointing noon spraying, after heading 11:00 until 16:00 after spray. Occurred heavier plots should be spaced 7-10 days and then spraying 1 - 2 times.

Hair dryer can blow flat curling wallpaper

Stylish appearance and environmentally friendly material, so dress up wallpaper become a modern family favorite. Wallpaper with a long time, there will inevitably be broken, curling the case,weed killer sprayer the following describes the processing method that allows wallpaper easily restored.

One problem: wallpaper curling

Workaround: Use wallpaper paste powder, wipe the curling place, the warped and hollows, with a hair dryer blowing about 10 seconds, and then hand in real until the cement with a hair dryer blowing dry.

Question two: wallpaper bubbles

Workaround: with a needle in bubbles on the surface of the garish wallpaper and release the gas, using a needle extract the right amount of adhesives, injection needle, which was then driven scraper flat compacted.

Question three: there are stains on the wallpaper

Workaround: drinks, beer and other liquids spilled wallpaper easily with a chemical reaction, can be used to garden sprayer backpack spray the cleaner spray stains, rub with a cloth kept turning in circles, stains will gradually disappear.

Remember that a single use of pesticides

Long-term use of a single pesticide resistance increases every year . In the course of the use of pesticides , pesticide control effect once found a good, long-term continuous use, even anti- drop effect is not replaced, that anti- drop effect is low pesticide content , did not realize that this is caused by long-term single use of a pesticide consequences. As 1978 6000 times with Fenpropathrin spider mite control , the control efficiency above 98%, now with 1000 times less than 50% control efficiency . backpack weed sprayers The country has more than 30 kinds of insects, 10 kinds of diseases that cause resistance to pesticides , farmers use to increase the dosage of the ways to improve the control effect , the results for the screening of the antibiotic into stronger offspring, continue to improve the drug concentration , worms resistant to further improve , resulting in a vicious cycle , do not solve the problem. Therefore, in the course of the use of pesticides , must pay attention to several pesticides alternating rotating, or reasonably mixed , thus extending the useful life and improve control effect.

Mixed use of pesticides, pay attention to a reasonable match. Should use a different mechanism of action of pesticides used interchangeably or in accordance with a reasonable physical and chemical properties of pesticides mixed use , so not only can improve the control effect,perfume sprayer but also delay the generation of pest resistance . Pesticide mixtures should pay attention to the following questions: ① after mixing pesticides increased efficacy or effect independently of each other , a

Pay attention to the effect of improving medication medication Flowers

1 dilution powder into a paste with water , and then multiple dilution ; cream , liquid in the sprayer should be loaded within 1/ 4 of the water and then poured into drug shake, and pour into the amount of water ; powder, emulsion and manure mixed , should be dissolved powder , adding 80 times of water , then mixed with cream , and finally mixed with fertilizer , red enough water chemical sprayer spraying. A variety of pharmaceutical and fertilizer mix , mixed with the use to be with , do not keep well , so as not to reduce the efficacy.

(2) the general dilution dilution 500-1500 times , pest prevention desirable when the minimum concentration ; pest control young desirability moderate concentrations ; peak and kill pests older , crusty pests , should take the maximum concentration . In floriculture , often is the same pest hazards, so sterilization, insecticide, fertilizer should simultaneously. But the pH of different agents can not be mixed fertilizers , and the mixture can not be more than three kinds . The mixing concentration of : barrel of water sterilizing agent 25-30 g , 20-25 g of pesticides , fertilizers and 50 grams.

3 application time and method of 17:00 ( positive leaves holes open ) liquid sprayer spraying absorb the best, and no sunburn , can reduce injury. Less easily decomposed in light use efficiency Zineb , Fenaminosulf , phoxim and other agents should be carried out on a cloudy day or in the evening , when it rains it rains before or not spraying . Spraying a mist as well, and the entire plant to be sprayed .

Tobacco scientific use of pesticides

Pesticides on the development of human civilization, agriculture has played an important role, especially in controlling risk , when the outbreak of pests and diseases , pesticides also show an irreplaceable role . However, in the course of pesticides on the air, soil and water will cause a certain degree of pollution, which requires scientific use of pesticides, with the least amount of the most effective pest control for maximum economic, social , ecological and environmental benefits.

In view of the status of tobacco production ,plastic sprayer  the State Tobacco Monopoly Bureau, Science and Technology Education proposed the development of "pollution-free tobacco " new ideas, relying on science and technology can make use of the use of pesticides near or at the effects of pollution . Despite the development of biological pesticides now in full swing, but it is widely used in the tobacco need to take time .

1 associated with the spraying of pesticides technical parameters

1.1 LD50 (ld50)

LD50 is the result of a biological experiment death of the individual populations of 50% of the dose. According to China Pesticide Toxicology grading standards , rat oral : ld50 <5mg/kg are highly toxic pesticides, such as " aldicarb " original drug ld50 of 1.0mg / kg; ld50 is 5 ~ 50mg/kg is a highly toxic pesticides such as " omethoate " original drug ld50 is 47mg/kg; ld50 of 50 ~ 500mg/kg belong moderately toxic pesticides, such as " fenvalerate " original drug ld50 is 451mg/kg; ld50> 500mg/kg belong toxicity pesticides, such as "In addition to bud through" the original drug ld50 of 1250mg / kg; ld50> 2000mg/kg are practically non toxic pesticides, such as pest control tobacco warehouse "insurable special" original drug ld50 is 34600mg/kg. ld50 reflect pesticides on the environment or the degree of harm to humans and animals by improving the formulation processing technology, can achieve low toxicity of highly toxic pesticides , toxic pesticide poisoning micro . weed sprayer Such as " decis " the active ingredient is " deltamethrin ", " deltamethrin " original drug ld50 is 138.7mg/kg, belonging to moderately toxic , processed into 2.5% EC ( " decis " ) after , ld50 is 535mg/kg, belonging to low toxicity pesticides. " Aldicarb " original drug is very poisonous, but commonly used to control aphids Tobacco 15% "iron aldicarb " granules (ld50 is 10.6mg/kg) is highly toxic .

1.2 Half-life (dt1 / 2)

Pesticide degradation half-life is a measure of the degree of difficulty of the targets. It reflects the pesticide sustained effect on pest control and pesticide residues levels. Long half-life of the pesticide persistence length to pests and diseases , can in a very long time to maintain the role of harmful organisms performance, but it is also the source of pesticide residue formation . dt1 / 2 <3 months of easily degradable pesticides ; dt1 / 2 of 3 to 12 months for the middle of pesticide residues ; dt1 / 2> 12 months for the long pesticide residues. Early use of arsenic , lead and mercury preparations half-life of 10 to 30 years ; half-life of organochlorine pesticides in 2 to 4 years , the half-life of organophosphorus pesticides are generally a few weeks to a few months ( " phoxim " the half-life in soil is 34d),water sprayer  carbamate pesticides generally only a half-life of ~ 4 weeks ( " aldicarb " In the half-life of fresh tobacco 14.4d), pyrethroids , sprouting products and herbicides half-life of a few days ( " deltamethrin " In the half-life of fresh tobacco 2.1 ~ 4.2d; " in addition to bud through" in the half-life of fresh tobacco 2 ~ 4d; Napropamide in the half-life of fresh tobacco 3 ~ 4d).

Tobacco Vegetable Production

Tobacco contains nicotine, nicotine insecticidal effect on humans, animals and the environment and will not cause any damage. Tobacco use in ancient China , there leachate control of plant pests records.bottle plastic sprayer Tobacco root , leaf and stem contains a lot of nicotine . Cigarette factory production process produces smoke dust, tobacco stems , moldy tobacco, tobacco, tobacco growers managed to lay a smoke when the top , the smoke of a tree, the old diseased leaves , harvest stem and root residues , etc., can be used to prepare the crude extract preparation.

Mode of action : contact and stomach poison, aversion and fumigation .

Control target: various vegetables aphids, cabbage worm , leafminers , mites, cabbage webworm and onion thrips .

Preparation and use: 1kg chopped tobacco leaves and stems in 15L water soak for 24 hours, plus a small amount of soap do emulsifiers, tobacco residue filtered after 24 hours , with a small piece spray garden water sprayer spraying.

How to prevent chlorine poisoning

Chlorine is the paper industry is one important chemical raw material , but also a strong toxic gases. In the production process due to improper operation, equipment, pipe leakage reasons, often chlorine escape, pollute the environment and endanger human . Long-term low concentrations of chlorine in the work environment for operators on how to prevent poisoning ?

According to the information , when the concentration of chlorine in 1PPM (1mg/cm2) below has little effect on the human body , but when the concentration exceeds 3PPM when you feel uncomfortable.

Chlorine is harmful to the human body , to prevent and reduce chlorine poisoning. The first is to strengthen the sense of responsibility, strict compliance with the process safety rules and operations , followed in the production process of the chlorine gas pipelines, gaskets, valves, etc. should be regularly checked and found leaks must be promptly replaced . Check for leaks available low pressure sprayerchlorine or ammonia rubbed with a brush dipped law . Because ammonia and ammonium chloride, chloride will be generated in the air to form white smoke . Third , the need for the prevention of poisoning and poisoning the necessity of self-help and mutual aid when knowledge and education . If they do not appear next to the escape of chlorine gas masks , the available water soaked towel handkerchief masks or cover your nose and mouth, quickly evacuated to the ventilation direction , and quickly correct wearing gas masks cut off the source of leakage of chlorine .

When using liquid chlorine cylinder , due to thermal expansion than just bottles of liquid chlorine thermal expansion coefficient a few times, so the liquid chlorine cylinder storage , transport, use, must be non-collision , exposure or baking to prevent cylinder explosion .agricultural sprayers  After chlorine chlorine cylinder filling , storage time should not exceed three months.

Knapsack sprayer fired rice pests " annihilation

Recent positive hybrid rice tillering to jointing stage round stalk , due to climatic reasons , leaf roller and planthoppers intrusion, the main hazards to feeding rice leaf roller Inaba , causing Inaba rolled up , the whole white leaf blight , leaf photosynthesis can not be normal , empty husks rate increased , weight decreased, resulting in production. The clump of rice planthoppers will base sucking sap that is harmful brown necrosis, nutrients and moisture loss , causing yellow leaves , growth low , seriously affecting rice production . " These two types of pest invasion , fast, fast breeding , harm is also large, large area by pest sprayer speed of fear is too late , using sprayer ideal ." Said the person in charge of plant protection station .

It is understood that , with the hand sprayer for pest control and disease prevention, slow, poor spray pesticides , loss, and the power of small spray , spray pesticides can only stay in the rice leaf surface and can not penetrate the rice plexus , resulting in pest control is not complete. The motorized sprayer reflected the effect is: spray speed, every seven minutes to complete an acre spray , spray with high pressure, good atomization , high utilization , the use of a pressure sprayer can be sent directly to the pesticide less Inaba position , can be full "destroy" pests and diseases. The knapsack sprayer spray rice and found that rice leaf surface , rice straw on pesticides has been atomized mist beads, pest and disease prevention effect is obvious. Large grain Zhang Mingsheng said: " We passed the preliminary conclusions drawn comparison test : manual sprayers can only complete one acre per hour spraying tasks, while sprayer reaches 10-12 acres per hour , a difference of 10 times ergonomics , and greatly reduce the labor intensity . knapsack sprayer because the pressure is high, thin cloud point , prevention is better than ordinary sprayers and spraying the machine back on the body , with the hand sprayer as easy . "

Local agricultural experts believe that the knapsack sprayer finish 50-60 acres per day , the cost of pesticides per acre savings of 17.9% . Use self-propelled sprayer indeed reduce the labor intensity of farmers and medication costs, improve production efficiency, pest prevention and control to ensure the effective time , to solve the security source management of rice diseases and insect pests . Limited Fusite this bottle sprayer , 2009 also supports directory into the country , in the work against the ruling system will flourish , full lay rice pest " war of annihilation ."
