What pesticides to use on watermelons for fast growth and high yield
In order to make watermelons grow fast and have high yield, it is necessary to spray pesticides, because there are many factors in the growth process of watermelons that affect their growth. Common diseases in watermelons include wilt and Fusarium wilt, which can be controlled by spraying 66.5% Proline 1000-1500 times liquid. Common pests include aphids and spider mites, which can be treated with 20% Kanfuduo emulsion in the early stage and 20% Mobilon emulsion in the middle stage by spraying.
Watermelon pesticide spraying
The yield of watermelons is related to the variety of watermelons planted. If well cultivated, large watermelons can yield about 7000 jin per mu, medium-sized watermelons can yield about 6000 jin per mu, and small-sized watermelons can yield 3000-5000 jin per mu.
If watermelons want to grow fast, it is necessary to control aphids, and spray dichlorvos and dimethoate 1:12000 times before planting, but attention should be paid to the application method.
Timing of pesticide application on watermelons
Watermelons are generally sprayed with pesticides every 7-10 days. Even if the seedlings are not treated for a month and the mature ones are not treated for half a month, 5-7 times of pesticide application are still required during the fruit-setting stage.
Pesticides for disease and pest control in watermelons
Common diseases in watermelons include wilt, T-J disease, and Fusarium wilt. After the watermelon seedlings emerge, they are prone to fall off. Spraying 66.5% Proline 1000-1500 times liquid or 64% alum wettable powder 400-500 times liquid can effectively control the situation.
Common pests in watermelons include aphids, spider mites, American leaf miners, and whiteflies. In the early stage, use 20% Kanfuduo emulsion or 12.5% Bilin solvent for spraying, generally with an interval of 15-25 days, and continue for 2-3 times.
In the middle stage, generally use 20% Mobilon emulsion spray, 1% Abamectin emulsion, or 0.5% Matrine aqueous solution for spraying, with an interval of about 7-10 days.
Taboos on the use of pesticides on watermelons
Pesticides for watermelons should focus on prevention, reduce the frequency of use as much as possible, and rotate the use of pesticides to avoid resistance. In addition, highly effective, low-toxicity, and low-residue pesticides should be used according to the operating procedures.
