New method for controlling mulberry pests

Abstract

The invention discloses a new method for controlling mulberry pests. In the technical scheme, the method comprises the following steps of: mixing 2 percent bitter general ginseng alkali and water in a volume ratio of 1:(600-2,500), spraying 45 and 55 kilograms of the mixture to leaf surfaces of mulberry in each 667 square meters of soil, and after applying for 4 hours to 5 days, picking leaves normally to feed silkworm. A pesticide prepared by the method is easy to prepare, wide in source of raw materials, low in price, non-toxic to human and livestock, pollution-free and convenient to use, and can be sprayed on the leaf surfaces of the mulberry directly, residues are avoided, mulberry leaves can be picked to be fed to the silkworm after several hours, and the mulberry leaves which are sprayed by the pesticide diluted by 2,000 times can be picked after 4 hours to be fed to the silkworm. Experiments indicate that the control effect on mulberry looper, euproctis similis, white tiger moth, large dagger moth, ascotis selenara dlanera hubner, pseudodendrothrips mori and red spider is 90 percent, and the control effect on mulberry pyralid moths and wild silkworm is poor (only 10 percent). The method is popularized and applied to about 3 hectares of mulberry fields in the Teyong town of Sheyang county and the Xinfeng town of Dafeng city of Jiangsu province, and the satisfied control effect is achieved.

Description

technical field [0001] The patent of the present invention relates to a new control method for preventing and controlling mulberry pests, especially a method that can be used in the sericulture season, has no pollution to the environment, is safe for humans and animals, and can be fed by picking leaves a few hours after spraying.
