Problems solved by technology

[0003] However, Metarhizium anisopliae is ineffective against other types of pests such as piercing and sucking mouth pests (aphids, planthoppers, etc.), and crops often have multiple pests concurrently when insect pests occur, especially the pests caused by Lepidoptera pests and piercing and sucking mouth pests. universal
Although Pentaclofen can simultaneously control the pests caused by Lepidoptera pests and piercing-sucking pests, its effect is still not ideal

Embodiment 1

[0029] Example 1: 14.7% Pentaclofen Metarhizium wettable powder

[0030] 0.7% of Pentametamidoguanidine, 14% of Metarhizium anisopliae, 6% of Chaku powder, 1% of ethanol, 5% of sodium lignosulfonate, and 100% of diatomaceous earth. The above raw materials are mixed according to the conventional method for preparing wettable powder, crushed to a certain fineness, and then mixed into a product to obtain 14.7% pentametamiclon·metrhizium anisopliae wettable powder.

Embodiment 2

[0031] Embodiment 2: 48% Pentaclofen Metarhizium wettable powder

[0032] Pentametamidoguanidine 3%, Metarhizium anisopliae 45%, Chaku powder 5%, Ethanol 1.5%, Sodium lignosulfonate 4%, Diatomaceous earth make up 100%. The above raw materials are mixed according to the conventional method for preparing wettable powder, crushed to a certain fineness, and then mixed into a product to obtain 48% pentametamiclon·metrhizium anisopliae wettable powder.

Embodiment 4

[0035] Example 4: 60% Pentamicloguanidine Metarhizium anisopliae water dispersible granules

[0036] Pentaclofen 40%, Metarhizium anisopliae 20%, Sodium Lignosulfonate 5%, Ammonium Sulfate 2%, Polycarboxylate 4%, Starch 1.5%, Kaolin supplement 100%. The above raw materials were mixed according to the conventional method for preparing water-dispersible granules to prepare 60% pentametamiclon·metrhizium anisopliae water-dispersible granules.

Abstract

The invention relates to an insecticide compound with the complementary action and the synergetic effect. The insecticide compound comprises the active ingredients of guadipyr and metarrhizium anisopliae, wherein the weight ratio of guadipyr to metarrhizium anisopliae is (1 to 60):(70 to 1). Auxiliaries and fillers are added into the effective active ingredients to form wettable powder, water dispersible granules and a suspending agent. The insecticide compound disclosed by the invention can be used for delaying the generation of the pest resistance to insecticides and can be widely applied to the field of agriculture.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to an insecticidal composition containing pententa and metarhizium anisopliae. technical background [0002] Lepidoptera is the second largest order in Insecta, and most of them are quite important pests of vegetables. Because the larvae are omnivorous, large in size, eat a lot of food, and the adults have strong reproductive ability and large amount of eggs, they are extremely harmful to crops. Therefore, insecticides are commonly used in most farmlands to control Lepidoptera pests. However, the high-intensity use of chemical pesticides has exacerbated the development of pesticide resistance of such pests, increased the cost and difficulty of pest control, and resulted in serious pesticide residues in food and the environment. Metarhizium anisopliae has a very good effect on the control of vegetable Lepidoptera pests. It can parasitize a variety of pests, enter the pests through ...
