Problems solved by technology

At present, diatomaceous earth is mostly used as an auxiliary agent (such as a filler or a carrier) and is widely used in pesticide formulations to play a role in slow release, while other functions in pesticides are realized by adding other corresponding auxiliary components, such as increasing Efficacy agents, etc., which also lead to the complex compounding relationship of too many components in pesticide products, which affects the efficacy, and long-term use will also cause damage to the soil and the environment

Embodiment 1

[0036] Embodiment 1 A kind of wettable powder for controlling nematodes and red spiders

[0037] The components include: 1.8% of the original drug of avermectin, 12% of a wetting and dispersing agent, and up to 100% of diatomite; the fineness of the diatomite is 325 mesh.

[0038] The wetting and dispersing agent is naphthalenesulfonate formaldehyde condensate NNO.

[0039] Preparation:

[0040] (1) Mix the original drug of Abamectin and the wetting and dispersing agent evenly, and set aside;

[0041] (2) the mixture in the step (1) is pulverized by air flow;

[0042] (3) Mix diatomaceous earth with the mixture obtained in step (2) evenly, and pass the inspection.

Embodiment 2

[0043] Embodiment 2 A kind of wettable powder for controlling nematodes and red spiders

[0044] The components include: 0.5% of the original drug of abamectin, 10% of a wetting and dispersing agent, and up to 100% of diatomite; the fineness of the diatomite is 500 mesh.

[0045] The wetting and dispersing agent is sodium lignosulfonate.

[0046] Preparation method is with embodiment 1.

Embodiment 3

[0047] Embodiment 3 A kind of water dispersible granule for controlling nematodes and red spiders

[0048] The components include: 5% of the original drug of avermectin, 8.5% of a dispersant, 5% of a wetting agent, 5% of a disintegrating agent, 1.5% of a binder, and 100% of filler diatomite.

[0049] The dispersant is polyoxyethylene lauryl ether; the wetting agent is sodium lauryl sulfate; the disintegrating agent is sodium bicarbonate; and the binder is xanthan gum.

[0050] Preparation method: Mix the above components evenly, add appropriate amount of water (generally the moisture content is 15-20%) for kneading, and then carry out granulation, drying, screening, testing, and storage of each product in turn. Unqualified products Carry out kneading, granulation, drying, sieving and testing again until it is qualified.

Abstract

The invention belongs to the field of pesticides and particularly relates to insecticide composition for controlling nematode and mite pests. The insecticide composition is prepared from components asfollows: 0.5%-5% of abamectin and 70%-90% of diatomite, wherein the fineness of the diatomite is 325-500 meshes. The composition has good slow release effects, combines chemical and physical insecticidal mechanisms and can effectively control agricultural pests and provide multiple microelements required by plant growth.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to an insecticide composition for controlling nematodes and acarid pests. Background technique [0002] Root-knot nematode is a highly specialized omnivorous plant pathogenic nematode. It has a wide range of hosts and often damages dozens of vegetables such as melons, solanaceous fruits, beans and radishes, and can also spread some fungal and bacterial diseases. Root-knot nematode mainly damages the roots of various vegetables, because it is difficult to cure and is called vegetable "cancer". [0003] Spider mites, also known as spider mites, mainly harm various vegetable crops such as Solanaceae, Cucurbitaceae, Legumes, and Liliaceae. It is widely distributed in our country, with strong adaptability and wide transmission methods. [0004] Abamectin is a sixteen-membered macrolide compound widely used for agricultural or veterinary insecticide, acaricide, and nematode activity. It is pr...
