Embodiment 1～12

[0048] Embodiment 1~12 wettable powder

[0049]The hypersensitive protein, active ingredient B, dispersant, wetting agent, and filler are mixed, mixed uniformly in a mixing tank, pulverized by a jet mill, and then mixed uniformly to produce the wettable powder product of the present invention. See Table 1 for details.

[0052]

Embodiment 13～24

[0053] Embodiment 13~24 water dispersible granules

[0054] The hypersensitive protein, active ingredient B, dispersant, wetting agent, disintegrant, and filler are crushed together by airflow to obtain the required particle size, and then other additives such as binder (optional) are added to obtain granulation material. The water-dispersible granule product of the present invention is obtained by quantitatively sending the material into a fluidized bed granulation dryer for granulation and drying. See Table 2 for details.

[0059] Mix dispersant, wetting agent, defoamer, thickener (optional), antifreeze (optional) through high-speed shearing, add hypersensitive protein and active ingredient B, and use up the rest Ion water is supplemented, and ball milling is carried out in a ball mill for 2 to 3 hours, so that the particle size of all the particles is below 5 μm, and the suspension product of the present invention is obtained. See Table 3 for details.

Abstract

The invention discloses a pesticide composition comprising harpin protein and biological sources. The pesticide composition comprises an active component A and an active component B. The active component A is selected from harpin protein. The active component B is any one compound selected from abamectin, spinosad, emamectin benzoate and spinetoram. A weight ratio of the active component A to the active component B is 1:80-80:1. The composition provided by the invention can be used for controlling various pests, and has a significant synergistic effect. With the pesticide composition, a pesticidal spectrum is expanded, the dose of pesticide can be reduced, residue amount of pesticide on crops can be reduced, and environment pollution can be reduced. Also, effective fertilizer absorption of crops can be improved, the growth of crop disadvantaged parts is assisted, and water balance in the crops is regulated, such that the metabolic systems of crops are activated, crop cell growth is promoted, and root system activity is enhanced.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to the application of a pesticide composition containing hypersensitive proteins and biological sources on crop pests. technical background [0002] Harpin protein, a natural protein, can regulate the growth of tobacco and enhance the disease resistance of plants. [0003] Abamectin, spinosad, emamectin benzoate, and ethyl spinosad are all biological source insecticides commonly used in agriculture, and emamectin benzoate is referred to as "Emamectin benzoate". [0004] In the actual process of agricultural production, the most likely problem in pest control is the generation of pest resistance. The compounding of ingredients from different varieties is a very common way to control resistant pests. Different ingredients are compounded, and according to the actual application effect, it is judged whether a certain compound is synergistic, additive or antagonistic. In most cases,...
