Bemisia tabaci shows different damage symptoms to different plants. The damaged leaves of leafy vegetables such as cabbage and cauliflower are shrunk, yellowed, and withered; , the fruit is unevenly matured, whitefly has the characteristics of wide range of hosts, waxy body, overlapping generations, fast reproduction, many transmission and diffusion channels, and easy resistance to chemical pesticides. Adults with wings are easy to escape when spraying pesticides. The eggs are protected by the chrysalis, so it is difficult to achieve a radical cure with various control methods at present.

Abstract
The invention relates to the technical field of plant insecticides and particularly relates to a bemisia tabaci control agent. The control agent consists of the following raw materials: 0.2-0.3 part of glucose, 3-5 parts of urea, 0.05-0.06 part of fumaric acid, 0.03-0.035 part of niclosamideethanolamine salt, 2-3 parts of vitamin C, 500-580 parts of water and 10-15 parts of ethanol. The bemisia tabaci control agent is prepared by the following steps: heating water to 50-55 DEG C; adding the glucose, urea, fumaric acid and vitamin C and stirring till complete dissolution to obtain a solution A; mixing the niclosamideethanolamine salt and ethanol, and treating for 8-9 minutes at 300-350Mpa to obtain a solution B; and mixing the solution A and the solution B to obtain the bemisia tabaci control agent. In use, the bemisia tabaci control agent is directly sprayed to plant leaves.
Description
technical field [0001] The invention relates to the technical field of insecticides for plants, in particular to a Bemisia tabaci control agent. Background technique [0002] Bemisia tabaci is a new pest that has occurred in China in recent years. It harms tomatoes, cucumbers, peppers and other vegetables and cotton and many other crops. The overlap of generations in the field is extremely serious. Bemisia tabaci shows different damage symptoms to different plants. The damaged leaves of leafy vegetables such as cabbage and cauliflower are shrunk, yellowed, and withered; , the fruit is unevenly matured, whitefly has the characteristics of wide range of hosts, waxy body, overlapping generations, fast reproduction, many transmission and diffusion channels, and easy resistance to chemical pesticides. Adults with wings are easy to escape when spraying pesticides. The eggs are protected by the pupal shell, so it is difficult to achieve a radical cure by various control methods at...
