What kind of medicine should be used in the flowering period of grapes?

When planting grapes, we should pay attention to the prevention and control of diseases and insect pests. The prevention and control of grape florescence is very important. What kind of medicine should be used during the flowering period of the grapes?

1. Inflorescence exposure period: pesticides are generally not used during this period, if some green bug bugs seriously need to use pesticides. If there is a problem of element deficiency, a variety of trace elements need to be supplemented.

two。 Inflorescence separation period: during this period, it is mainly the prevention and control of Botrytis cinerea, downy mildew, black pox, ear axis brown blight and so on, while paying attention to the supplement of boron. Mancozeb and carbendazim can be used and pyrimidine can be added in the case of serious Botrytis cinerea in the greenhouse. For the problems caused by boron deficiency, such as falling flowers and fruits, fluid boron can be used. In this period, we should also pay attention to the prevention and control of spotted wax cicadas, if there are spotted wax cicadas, pay attention to the use of pesticides.

3. Early flowering: the purpose of pre-flowering prevention is to ensure the safety of flowering, no matter what varieties need to use pesticides for control, grape flowering is a relatively fragile period, so we must do a good job of prevention, while the need to supplement zinc and boron, to prepare for grape fruit setting. Before bagging after Xie flower, the medication should be adjusted reasonably according to the bagging time, and the medication before bagging is also the focus of prevention and cure. This should be adjusted according to the specific situation (bagging 3 days after medication), and pay attention to the use of foliar fertilizer. This period is generally more important for calcium supplement, calcium glycolate can be used to supplement the calcium deficiency of grape enlargement.

Grapes should do a good job of prevention before flowering, and it is best not to use drugs during flowering, so as to avoid falling flowers and fruits. If there are special circumstances, spray some low concentration drugs appropriately.
