What pesticides should be used on grapes to ensure good growth and high yield
It is important to apply pesticides during the cultivation of grapes to achieve a good harvest. To enhance the plant's resistance to stress, the use of compound sodium nitrophenolate aqueous solution is generally effective for preserving flowers and fruits. Of course, preventing diseases and pests can also preserve flowers and fruits. Dithiocarbamate, carbendazim, and thiram are all suitable. Before grape flowering, you can spray a 50% carbendazim solution diluted 500-600 times or a 70% methyl thiophanate solution diluted 800 times, and one application is sufficient.
Grape Growth Cycle
1. Germination stage: Keeping the temperature around 10°C will cause the buds to start sprouting, entering the germination stage.2. Shoot elongation stage: Two weeks after the grapevines sprout new buds, they will enter the shoot elongation stage, at which time the branches require sufficient nutrients to support their growth.3. Flowering stage: By June, grapes will gradually start to bloom, entering the flowering stage, which is part of the grape growth process.4. Fruiting stage: After the grapevines bloom, they will gradually produce fruit. By the end of June each year, the flowers will wither and fruits will appear.Grape Pesticide Application
The second and third leaf stages are critical periods for preventing various diseases and pests from infecting the plants, especially powdery mildew. There is another key control period during the young fruit stage. It is essential to promptly spray protective agents to prevent pests and diseases from infecting the tender branches and leaves. It is important to spray pesticides such as pyraclostrobin, pymetrozine (Y-J) class, or quinalphos, pyrethroids to focus on preventing green盲蝽.What pesticides should be used on grapes to enhance their resistance to stress and ensure the preservation of flowers and fruits.

What pesticides should be applied to grapes to make them grow fast? Before grape flowering, you can spray a 50% carbendazim solution diluted 500-600 times or a 70% methyl thiophanate solution diluted 800 times, and one application is sufficient. What solutions can make grapes bloom earlier and more frequently? Generally, applying phosphorus and potassium fertilizers is better, and monopotassium phosphate is good. Regularly spraying the leaves and branches with monopotassium phosphate will result in better and more vigorous growth, more blooms, and more fruit.What pesticides can prevent pests? After sprouting and before unfolding leaves, spray once with a necessary 400x solution. At 2-3 leaves, spray once with a 1500x solution of Shunbei Fumitox. Before flowering, spray once with a 600x solution of Penfu Lu and a 1000x solution of pyrimethanil. After flowering and before the clusters are sealed, use a 4000x solution of 97% myclobutanil and a 1500x solution of Shunbei Fumitox.
Grape Disease and Pest Prevention
Different varieties and growth stages have different diseases and pests, so the focus of control is also different, but there are three fundamental aspects: protecting the roots (overuse of fertilizers causes more root problems), protecting the leaves (the main leaf disease is downy mildew, with brown spot also common in the south, especially in Sichuan), and protecting flowers and fruits (mainly controlling black rot of the spike and gray mold).If the above information about what pesticides to use on grapes to ensure good growth and high yield is helpful to you, remember to visit our website often!
