How to improve the utilization of pesticides

Want to improve the utilization of pesticides , it is necessary to improve the quality of the manual spraying machine , spraying parts single change the status quo, to promote the upgrading of manual sprayers

Spray atomization quality is the determining factor , directly affect the deposition of pesticide on crops distribution . Droplet distribution density is related to the control effect is an important factor. The same amount of liquid, if the droplet size by half , and the resulting 8 -fold increase the number of droplets . Led the establishment of the National Agricultural Center in Shandong Wish Plant Protection Machinery Co. , development and production of the " Guardian " card WS-16 Type Sprayer , won the national key new product certificate and four patents, and has been the first to get "3C" certification, becoming the ideal replacement of manual sprayers varieties .

The implementation of low volume hand pump sprayers spraying technology to reduce the amount of liquid present Mushi

Crop leaf surface can be attached pesticide droplets is limited , when spray volume exceeds a certain limit , the leaves on the tiny droplets will agglomerate into large droplets and rolled , the loss , but to make the blade attached to the drastically reduced the amount of pesticides . Spray volume in developed countries are generally controlled at 100 per hectare - 300 l range , less spray volume per unit area of 1/3 , and thus the loss was minimal, pesticide utilization is higher.
