Based on the occurrence law of diseases, insects and weeds in the field of strip compound planting, the prevention and control strategy of "one application for multiple treatments, one plant for multiple inducements, and combination of seals and seals" has been formulated.
One Shiduozhi:
Aiming at the same occurrence period and common diseases and insect pests of corn and soybean, during the critical period of disease and insect pest occurrence, broad-spectrum biocontrol agents, agricultural antibiotics, high-efficiency and low-toxicity insecticides, fungicides, combined with pesticide synergists, are used to treat a variety of diseases and insect pests. Carry out unified control to achieve the goal of one-time spraying and control of multiple diseases and insect pests.
A lot of temptations:
Aiming at the occurrence of pests in strip compound planting, based on the physical and chemical principles of phototaxis (insecticidal lamps), chromotaxis (swatches), chemotaxis (sex attractants) and other physical and chemical principles, intelligent controllable multi-band LED insecticidal lamps, degradable Physical instruments such as multi-color plates and sexual attractant devices can simultaneously trap and kill the main same and common pests, and achieve the goal that one instrument can trap and kill multiple pests through artificial or intelligent control.
Sealed combination:
According to the selectivity of corn and soybean to herbicides, weeds were controlled by a combination of pre-emergence blocking and post-emergence directional weeding.
The new planting model combined with the sensitivity of soybean to broadleaf selective herbicides has put forward new requirements for the use of herbicides in compound planting.
Pre-emergence closed weeding:
The recommended varieties are 96% metolachlor emulsifiable concentrate, 50% methoxazone WP; if there are many weeds between the corn rows, 4 to 7 days before sowing soybeans, use 50% ethyl acetate Glucosamine EC + 41% Glyphosate Water is used together.
Post-emergence directional weeding:
Inappropriate selection of herbicides or excessive application can easily lead to phytotoxicity, so the selection of post-emergence herbicides for soybeans or corn is very important.
Recommended drugs for corn seedling stage:
75% thifensulfuron or 96% metolachlor EC + 20% isooctyl chlorofluoroacetate EC, or 4% nicosulfuron can be used at the 2-4 leaf stage of corn Suspension agent + 20% chlorofluoropyridine isooctyl acetate EC, directional spray.
Soybean seedlings are dominated by grass weeds, you can choose 25% fomesafen water or 10% quizalofop-ethyl emulsion mixed with 25% fomesafen or 5% quizalofop emulsifiable concentrate or 24% clethodim EC or 10.8% high-efficiency chlorfenapyr EC, directional spraying.
For the herbicides such as atrazine and mesotrione that are routinely used in corn, it is recommended to use the recommended agents instead to avoid phytotoxicity to soybeans.
Regarding strip compound planting, the focus of chemical prevention and control is still on the prevention and control in the early stage. Reduce the base number of weeds and initial insect sources in the field, and provide a good growing environment for the growth of soybean and corn.
