Summer corn field herbicide five attention
The growth period of summer maize coincides with the rapid growth of weeds in the high-temperature, high-humidity seasons, coupled with the fact that rain is more artificial and mechanical control of weeds is more difficult. Farmers are increasingly accepted and commonly used for chemical weeding in corn fields. The wide variety of corn herbicides used and the high technical requirements may cause phytotoxicity to corn. The following five points are notes on the use of herbicides in summer corn fields:
First, if we have a large amount of weeds in the ground after the wheat is harvested, all herbicides must be used. Glyphosate is a systemic herbicide that does not show any effect in the early stage after spraying, but about two weeks later, weeds will die from the roots.
Secondly, the herbicides that are excavated from weeds include the ethylene mixture, the jade grass net, and the duolin mixture. Generally, 200 grams per mu is used, and 45 kg of water is used. If the amount of water is small, the drug sealing layer is thin, and some highly resistant weeds can easily drill out the sealing layer, resulting in poor control efficiency. However, the amount of water can not be too large, otherwise the effective concentration of the agent will decrease, and no blocking effect will be achieved.
Thirdly, once the above-mentioned closed herbicides come into contact with cotton, peanuts, soybeans, and vegetables, they will have different degrees of phytotoxicity. Therefore, when spraying the above herbicides, the following principles must be followed: Spray as much as possible in the absence of wind, and prevent the use of pesticides. Winds are transported to vegetables, peanuts and other crops; sprays are sprayed after lowering the nozzles to minimize the drift of the chemicals; protective covers and directional sprays are used in front of the spray heads.
Fourth, in recent years, due to the poor use of closed herbicides in some areas, some farmers’ friends, such as corn and weeds, have grown up and weeds with herbicides such as Yule Farm and Yuheng. However, farmers' friends should be reminded that the best time for prevention and control is when 4 to 5 leaves of corn and 3 to 4 leaves of weeds are used. If the corn is used for control after 7 leaves, it may cause injury.
Fifth, pests in corn fields can be mixed with insecticides and herbicides. However, they can not be mixed with organophosphorus pesticides with herbicides, such as Yunongle and Yuheng, and can only be mixed with pyrethroid pesticides. Care should be taken when using them. Look at the instructions.
