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 ."

Paddy emergence herbicide injury countermeasure

Chemical weeding efficient, thorough , labor , time , help large scale mechanized operations, efficient agriculture has become an indispensable important measures. However, due to the improper selection or spraying herbicides wrong way, the season or after the crop to cause serious injury to occur. Once phytotoxicity science should take timely countermeasures .
First, rule out the use of herbicides drug excessive drug toxicity , injury has occurred or will occur , to take early measures to detox . Immediately drain the water contained in the field of irrigation , several consecutive flush with the new irrigation, drainage facilities into lime or a combination of other methods , and in the fields of acidic herbicides, reducing the content of herbicides in soil ; medicine for plants harm , garden sprayers the available water irrigation machinery residue leaching of toxic plants , reducing the poison stick on the leaf . Severe poisoning plots should be rinsed after exposure to deep plowing , and then try to grow a small amount of sensitive crops can observe two weeks to prove that no injury again when other crops .
Second, to strengthen field management of crops on plots by the injury , to strengthen field management , the use of fast-acting fertilizer by Shi , scientific management, to reduce the impact of herbicides on crops , to reduce the losses down .
Third, the application of plant growth regulators to promote crop growth plant growth regulator is to promote crop growth agents, it has a good crop growth stimulation , but also help reduce injury .
Fourth, the use of chemical antidotes dressing with activated carbon can reduce or prevent four alachlor , linuron ,24-D herbicide phytotoxicity to corn , but also in plants before planting their roots or stems dipped in powdered activated carbon , can prevent injury. Planting the crop every 15 mu 10-40 kg evenly spread on the soil surface , can also be sprinkled on the soil surface to prevent local or ribbon simazine on soybean , cucumber, wheat injury. Naphthalene dicarboxylic anhydride is used to prevent EPTC injury to corn , the usual dose is 0.15% of the seed weight ,pressure water sprayer the effect is better. CGA-43089 for sorghum seed dressing to prevent isopropyl amine, acetochlor on sorghum injury. General sorghum seeds per 1 kg 1.25-1.5 g up control effect.

Paddy herbicide phytotoxicity main treatment measures

 1 irrigation detox . Soil caused due to excessive pesticide phytotoxicity , can be repeatedly washed irrigation fields . 2 agricultural sprayer wash seedlings . Concentration is too large , or the use of foliar injury caused by excessive absorption , continuous spray rinse , reduce the concentration of the drug on the rice plants .
3 antidote . According to the nature of the injury , the choice of appropriate drug detoxification remedy. Some Plant Growth Regulators can be used as a herbicide antidote. Such as spraying modest " 920 " , can ease the extent of the injury .
4 topdressing fertilizer. Timely removal of injured leaves , increasing livestock manure composting facilities , such as urea fertilizer available , can promote root development and regeneration of new leaves .
5 foliar spraying . Yemianpenfei , rice plants absorb quickly . If using 0.1-0.3 % potassium dihydrogen phosphate or phosphorus and potassium fine, Penshibao etc. foliar fruit tree sprayers can promote rice root development , to restore growth .

The use of chemical pesticides can not be arbitrary

Farmers can not blindly mixed pesticide use in order to save labor, and to consider a variety of disease prevention and control, or another disease prevention and pest control, often several pesticides sprayed mixed results and some produce injury, and some failures (acid-base neutralization), Some toxicity increased, causing poisoning and even death. So, should scientific medicine.

To pay attention to safety when spraying backpack chemical sprayers spraying, wear a mask, plastic gloves, goggles, hand-mixed drugs is strictly prohibited. Sprayer when problems arise, not directly nibbled, mouth suction. After spraying medicine, use soapy water and rinse hands clean. If dizziness, nausea, stop spraying, to fresh air and rest, if poisoned, should go to hospital symptomatic treatment. To take good care of pesticide use should be finished bottles buried, not for containing other items.

To comply with regulations on highly toxic pesticides such as phorate, Suhua 203, one thousand six hundred and five, methyl six  zero five one thousand and fifty-nine, fenitrothion Granville, flower sprayer long validity spirit, phosphorus amine, methamidophos, isopropyl phosphorus, three parathion, omethoate, zinc phosphide, aluminum phosphide, cyanides, carbofuran, fluoroacetamide, arsenic, chlordimeform, West Lik Sang, Saili scattered, ulcers net, chloropicrin , pentachlorophenol, DBCP and so on. And high pesticide residues, such as BHC, DDT, chlordane and other pesticides, the state has expressly provided, are not allowed to use on vegetables. However, some farmers still secretly uses a six  zero five maggot control leeks, use of methamidophos prevention moth, aphids and other use of carbofuran, the result of consumers eating these vegetables, the cause poisoning, serious consequences.

Bee Disease Control and Prevention

1 Disease Prevention

There are a variety of bee diseases, in order to prevent bee diseases, harm bees, must carry out the principle of prevention, usually to strengthen the feeding and management of bees, back pack sprayer bee farm environment and attention beehive, honeycomb, bee hygiene. On the beehive, honeycomb, bee and venue for disinfection and sterilization. A small amount of lime available to open, the preparation of 10% to 20% of the milk of lime, evenly sprinkle on the bee farm or stucco walls. Or with 2% caustic soda solution was washed larvae larvae rancid disease and cystic disease contaminated hives and nest boxes, and then wash with water. For small tools, such as cover cloth and clothes can be 2% to 5% soda solution to clean. Meanwhile bee species to choose disease-resistant, keeping strong group, the introduction of quarantine must be carefully when bees. Fangfeng site requirements ventilated and dry, less than Fangfeng bee diseases endemic areas. Once a bee disease and early treatment should be promptly isolated to prevent the spread of the disease caused economic losses.

2 methods given medicines

Bee disease is given medicines given medicines during the day using the spray method spleen, splenic given medicines at night using an empty method. Method is to spray the spleen given medicines decoction after cooling, spray lightly with a clean, non-toxic spray to the honeycomb, the spraying amount of each bee can be stained with sticky syrup without wings is appropriate, at intervals of 2 ~ 3 hours 1 spray better. Empty spleen given medicines France is suffering at the 2nd stew by adding honey 50 grams or 100 grams of sugar, and then poured into the two sides of the spleen, for the bees at night to eat.household sprayer If the edge of the spleen pile beam sprinkle a little honey, bee foraging disease lure more and better efficacy.

Catfish fish rice farming pesticide application methods to properly

Depending on the circumstances , selective spraying using the following method .

( 1 ) Sham spraying method

In the fish before the first application of pesticides in paddy field water deepened, flooded field surface 7 to 10 cm , such as a larger concentration of pesticides can be further deepened some of the fields of water , diluting the concentration of the liquid in the water , reducing or avoiding fish hazards. With a pore size bottle sprayer, sprinklers should upward sweep of rice stems and leaves, try spraying the drug in the rice leaf surface , reducing pesticide falling into the water field .

( 2 ) Drainage spraying method

Water off the field before treatment , exposing the soil surface , so that the fish concentrated in fish ditch, the fish slipped , and then spraying pesticides attention can not be applied into the ditch fish , the fish slipped in . Tanaka toxicity of pesticides to be degraded , and then further to the normal water depth of field .

( 3 ) The next sub- spraying method

First half a field or fields in a certain part to fight drugs , fish can not escape to another part of Tanaka fight drugs , the next day and then in another part of the Tanaka spraying.

( 4 ) water spraying method

Pesticides can also be applied to the inlet and outlet open, so that the water flow field , starting with the outlet of a pesticide , applied to the fields intermediate pause, to make contaminated water out of the field , and then applied to the intake from the middle at the end .

( 5 ) timing spraying method

Use powder pesticide manual sprayer spraying in the morning , because the morning Inaba , rice straw on the dew, most adherent powder , thereby reducing pesticide into the water . Use liquid, emulsion pesticides should be applied after the 16:00 ; summer temperatures should be in the 17 o'clock after spraying, reduce pesticide toxicity to fish . Do not raining or rain before spraying pesticides or pesticide will be washed into the water field , easily lead to fish poisoning.

Pay close attention to fish after spraying activities , such as found with symptoms of poisoning , you must immediately add new water , the best part of the discharge side of infusion of new waterside field water dilution water concentration to avoid fish poisoning .

When using herbicides influence of temperature on the efficacy of

When using herbicides influence of temperature on efficacy , generally only postpone or advance the efficacy of play time . If the temperature is low , due to the physiological activity of weeds is also relatively slow , and thus the conductivity also slow the absorption of herbicides , such as winter or spring, and thus the efficacy of performance when backpack weed sprayers spraying time , and compared to the hot summer months , generally extending 5 10 days or even longer. This is why the temperature is low more than 10 days after the use of herbicides , the weeds are not symptoms of poisoning. Currently on the influence of temperature on herbicide roughly as follows: the temperature is below 10 degrees Celsius, most of the herbicide efficacy is difficult to play, as the temperature gradually increased gradually shown efficacy, if prolonged continuous low temperature , herbicides lose part of the effect will be weathered ; 10 degrees Celsius, most of the herbicide can show herbicidal effect , but higher than under normal circumstances, be delayed 5-10 or so ; 15 degrees Celsius, herbicide efficacy normal play ; 15-35 degrees Celsius between efficacy with increasing temperature performance faster. But not the higher the temperature the better.

And herbicides for families and genera close to target plants lawn grass, under any circumstances do not arbitrarily increase the dosage , or carried out under the guidance of technicians spraying . Grasses such as Kentucky bluegrass lawns in using consumer bluegrass, miscellaneous consumer controlling crabgrass, goose grass and other weeds ; using clover in clover music broadleaf weeds ; lawn in Golden Horseshoe Horseshoe Net Control in use broadleaf weeds , etc., are not arbitrarily increase the dosage.

For more emaciated weeds , leaves small, upright weeds , control method can be used when spraying twice . As used in bluegrass lawns eliminate Wo controlling weeds crabgrass, the dosage is 90 ml per acre , you need to be watered 25-30 kg evenly spraying . We can eliminate the first use of 45 ml Wo watered 25-30 kg spraying a mu of land, the next day using 45 ml elimination Wo watered 25-30 kg spraying a mu of land, is better than a sufficient amount of perfume sprayer spraying the herbicidal effect .
