Weeding in wheat fields

Timely weeding is very important in the growth of wheat, because too much weeds will seize the nutrients from wheat and cause wheat to fail to grow properly. In addition to selecting suitable herbicides for weed control in wheat fields, it is also important to grasp the right timing of application.

According to the type of weeds in wheat fields, they can be divided into broad-leafed grasses and grasses. Suitable herbicides for broad-leaved grasses include tribenuron-methyl, bensulfuron-methyl, ethyl flufenazone and thifensulfuron-methyl. Fluroxypyr, flufenazone, imidazolam, flufenoxan, dimethyltetrachlorodichloromethane, tetracycline. Herbicides suitable for grasses in wheat fields include: oxazolyoxime, clodinafop-propargyl, dimethylsulfuron, and flucarbazone.

Normally, farmers' friends will spray pesticides before wheat emergence, and then spray them again after emergence. Therefore, many farmers will choose the season of wheat weeding in the spring, until weed grass age and density are very Only when the drug control. In fact, this is very unscientific, because at this time the weeds are old and the drug resistance is increased. Therefore, it is necessary to increase the amount of drugs when they are controlled. This will increase the cost and cause phytotoxicity to wheat, postharvest and adjacent crops.

In fact, the best period for chemical weeding in wheat fields is the winter wheat tiller and the early wheat jointing year. At this time, the effect of medication is better, and it is safer for wheat, and it is worse at night. Among them, the sooner the better, the better the use of 2,4-D butyl ester. Tribenuron is best used before the wheat turns green to avoid the next Crops produce phytotoxicity.
