Problems solved by technology

However, since the above-mentioned ingredients can only play a corresponding control role after contacting the corresponding insects and other pests, and the contact with the insects is a passive state, it cannot actively attract insects or actively adsorb on the surface of insects to play a more efficient role. The effect of controlling pests
In addition, due to the above-mentioned structural characteristics of the diatomite having a zigzag honeycomb structure, the diatomite cannot be pulverized or violently stirred, which affects the dispersion of functional components and the exertion of efficacy to a certain extent.

preparation example Construction

[0053] A third aspect of the present invention provides the preparation method of the biopesticide insecticidal wettable powder as described above, which includes the following steps:

[0054] (1) Add the active ingredient of the attractant and the dispersant in the formula amount into the reactor, stir and mix to obtain the A component;

[0055] (2) Add the specific structure diatomite and the remaining raw materials into the A component and mix.

[0056] In some embodiments, vibration mixing or stirring mixing is selected in step (2); when stirring mixing is used, the stirring speed is not higher than 80 r / min. Preferably, when stirring is used for mixing, the stirring speed is 70 r / min.

[0057] Through the solid surfactant with specific structure, the anionic second dispersant and synergist with comb structure of the present invention, the diatomite structure with specific structure can be protected from being damaged during the preparation process of the composition, whi...

Abstract

The invention relates to the technical field of pesticide compositions, and concretely relates to a biopesticide insecticidal composition, and a preparation method and application thereof. The composition comprises a diatomite with a specific structure and an attractant active component in a weight ratio of (1: 80) to (80: 1), wherein the diatomite with the specific structure has a zigzag honeycomb structure; and the diatomite of the specific structure is Celite610. On one hand, the adopted diatomite has the specific zigzag honeycomb structure, so that better adsorption to a wax coat on the body surface of an insect is facilitated, and rapid dehydration in the body of the insect is caused; and on the other hand, the wax layer on the body surface of the insect can be easily damaged, the body surface of the insect is torn, and the wax rapidly permeates into the body of the insect to cause fatal damage to the insect. And after the diatomite with the specific structure is compounded with insect attractants such as n-hexanol, 6-methyl-5-heptene-2-one and the like for use, the original passive contact of the composition for preventing and controlling pests is changed into active attraction, so that the preventing and controlling efficiency of the composition is further improved.

Description

technical field [0001] The invention relates to the technical field of pesticide compositions, in particular to a biological pesticide insecticidal composition and its preparation method and application. Background technique [0002] At present, chemical agents are mainly used to prevent and control pests at home and abroad, and a large number of pest losses have been recovered. However, long-term use of chemical agents has serious problems such as agent residues, environmental pollution, pest resistance, and pest re-emergence. Therefore, it has become an urgent task to reduce the use and phase out of chemical pesticides with toxic and side effects, develop non-toxic and harmless pesticides with no harmful residues, or low toxicity and high efficiency, and explore new methods of pest control. [0003] Invention patent CN101297652B discloses the application of silicon dioxide in the preparation of medicines for preventing and controlling pests and other arthropods, and its e...
