Abstract

The invention provides a method for preventing watermelon fruits from pesticide pollution and disease and pest damage. High temperature and high humidity weather in a greenhouse are easy to induce the disease and pest damage of watermelons, and the normal control method is to spray pesticides. With the increasing of use frequency of the pesticides, the pesticide application quantity is increased, the pesticides remained on the fruits are continuously increased, so that the edible safety of the watermelons in the market is becoming more dubious. The invention provides a method for preventing the watermelon fruits from the pesticide pollution and the disease and pest damage, the problem that the watermelon fruits are easy to be polluted by the sprayed pesticides is solved by uniformly spraying polyvinyl alcohol solution on the withered watermelon fruits at one step, and moreover, the damage of various bacteria and pests suffered by the watermelon fruits during expanding can be prevented; the pesticide application quantity is reduced, and beneficial conditions for producing high-quality and nuisanceless watermelons are created.
