Grape pest control should be prevention-oriented, but the grape varieties have different resistance, different regions, different cultivation methods, and the focus of prevention and control will be different. Regardless of the area, pre-flowering control is critical, but for each region, the drug cycle needs Make adjustments and find the right medicines and methods for your area.
First, before germination
Mainly do a good job in the Qingyuan, killing the source of the wintering bacteria, the source of insects.
General use of stone sulphur mixture, the use of stone sulphur mixture in greenhouses, do not contaminate the shed film, for serious diseases can use triazole agents, such as tebuconazole, hexaconazole and so on. The northern open-air grape is recommended to be used after being put on the shelf. Generally, it is better to spray after being put on the shelf than without the shelf.
For areas with severe white rot last year, some used thiram first, and seven days later, stone sulphur mixture was used for prevention.
Second, 2~3 leaf stage
Mainly pay attention to the prevention and treatment of green blind mites, scale insects, powdery mildew and black pox. Most areas are mainly the prevention and control of green blind mites.
Generally used according to the situation, spider mites and the like need acaricide, such as avermectin, phlegm, matrine, etc.; green blind mites need to use insecticides, such as high-efficiency chlorocyanide, imidacloprid and so on. It can be combined with a fungicide to prevent powdery mildew. For example, copper preparations + insecticides, or thiram + insecticides can be used.
Bordeaux mixture is a copper preparation that is often used before flowering, but the Bordeaux mixture currently has poor stability and is easy to contaminate the leaves, and can be selected as ready-made preparations.
Third, the inflorescence exhibition period
This period generally does not use pesticides, and if there are some green blind mites, serious insecticides are needed. If there is a shortage of problems, you need to add a variety of trace elements.
Fourth, inflorescence separation period:
During this period, it is mainly the control of gray mold, downy mildew, black pox disease, cob brown blight, etc., while paying attention to boron supplementation.
Mancozeb, carbendazim, etc. can be used, and pyrimethanil can be added in the case of serious gray mold in greenhouse. Fluid boron can be used for problems such as falling flowers and fruit that are easily caused by boron deficiency. At this time, we must pay attention to the prevention and control of spotted wax mites. If there is a spotted wax mites, pay attention to the use of insecticides.
Fifth, the initial flowering period
The purpose of pre-flowering prevention is to ensure the safety of the flowering period. No matter what kind of variety, it is necessary to use pesticides for prevention and control. The grape flowering period is a relatively fragile period, so it is necessary to prevent it, and at the same time, it needs to supplement zinc boron to prepare for grape fruit setting.
Carbendazim, thiophanate-methyl, etc. are generally used. At this time, it is necessary to add fluid boron and need to supplement zinc.
For the case of severe inflorescence rot in the previous year, it can be prevented by using diazepam + thiophanate-methyl.
Try not to take medicine during the flowering period. If you need to take medicine in special circumstances, try to avoid the flowering period.
After Xie Hua, before bagging, adjust the medication according to the bagging time reasonably. The medication before bagging is also the key point of prevention and control. According to the specific situation, the medicine should be adjusted according to the specific conditions (3 days after the medicine is applied), and the foliar fertilizer should be used. The period is generally more important for the supplement of calcium. Calcium alcohol can be used to supplement the calcium deficiency problem of grape enlargement.
For the entire post-administration, the drug regimen is determined mainly according to the specific situation, and at the same time, the drug is treated alternately throughout the production cycle to prevent drug resistance.
