Problems solved by technology

[0003] Spodoptera frugiperda, belonging to the family Noctuidae of Lepidoptera, has strong fecundity and environmental adaptability, and it is easy to develop resistance to various types of insecticides. The resistance to formamide and cyantraniliprole develops slowly. However, when such insecticides are used for seed treatment, the effect is slow, and effective control cannot be carried out in the early stage of crop growth. When made into granules, the drugs are easily degraded. This leads to poor drug efficacy and it is difficult to play a control role. In addition, the problem of drug resistance of fall armyworm also needs to be further solved

preparation example Construction

[0039]The second aspect of the present invention provides a method for preparing the above-mentioned pesticide granules for preventing and controlling Spodoptera frugiperda, comprising the following steps: weighing active ingredients, plant growth regulators, binders, dispersants, and water, and mixing uniformly Then use the carrier to absorb, that is.

[0040] The third aspect of the present invention provides an application of the above-mentioned pesticide granule for preventing and controlling fall armyworm, which is used for seed dressing with crop seeds to control fall armyworm.

Embodiment 1

[0044] Example 1 provides a pesticide granule for preventing and controlling Spodoptera frugiperda. In parts by weight, its preparation raw materials include: 5.5 parts of active ingredients, 4 parts of plant growth regulators, 2 parts of binders, 0.5 parts of dispersants, 2 parts of water, 80 parts of carrier.

[0045] The active ingredients are cyantraniliprole (CAS No.: 736994-63-1) and indoxacarb (CAS No.: 144171-61-9), and the weight ratio between them is 7:4.

[0046] The plant growth regulator is jasmonic acid (CAS number: 77026-92-7).

[0047] The binder is xanthan gum (CAS number: 11138-66-2).

[0048] The dispersant is polycarboxylate (CAS number: 62601-60-9).

[0049] The carrier is clay; the clay is modified clay; the preparation method of the modified clay is as follows: uniformly mixing clay and phospholime at a weight ratio of 1:0.8 to obtain the product.

[0050] This example also provides a preparation method of the above-mentioned pesticide granules for pr...

Embodiment 2

[0053] Embodiment 2 provides a pesticide granule for preventing and controlling Spodoptera frugiperda. In parts by weight, its preparation raw materials include: 5.5 parts of active ingredients, 4 parts of plant growth regulators, 2 parts of binders, 0.5 parts of dispersants, 2 parts of water, 80 parts of carrier.

[0054] The activity is known as cyantraniliprole.

[0055] The plant growth regulator is jasmonic acid.

[0056] The binder is xanthan gum.

[0057] The dispersant is polycarboxylate.

[0058] The carrier is clay; the clay is modified clay; the preparation method of the modified clay is as follows: uniformly mixing clay and phospholime at a weight ratio of 1:0.8 to obtain the product.

[0059] This example also provides a preparation method of the above-mentioned pesticide granules for preventing and controlling Spodoptera frugiperda, comprising the following steps: weighing active ingredients, plant growth regulators, binders, dispersants, water, and mixing the...

Abstract

The invention discloses pesticide granules for preventing and treating spodoptera frugiperda. The pesticide granules comprise the following preparation raw materials in parts by weight: 1-10 parts ofan active component, 1-10 parts of a plant growth regulator, 1-10 parts of an adhesive, 1-10 parts of a dispersant, 1-10 parts of water and 40-100 parts of a carrier. By adopting the pesticide granules, resistance development of the spodoptera frugiperda can be effectively retarded, on one hand, effects of the active component can be taken into play rapidly in seed treatment, the chemical effect is stable, an excellent prevention and treatment effect is achieved for insects, and on the other hand, the insect resistance of crops selves can be improved.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a pesticide granule for preventing and controlling Spodoptera frugiperda. Background technique [0002] Fall armyworm is an agricultural pest with strong adaptability and migration ability. Its native place is the Americas, but now its damage has spread to the whole world. In January 2019, it invaded from Southeast Asia to Yunnan, my country. It took less than half a year to die. It has spread to 18 provinces and cities across the country, and continues to move northward, seriously threatening my country's food production, especially corn crops. [0003] Spodoptera frugiperda, belonging to the family Noctuidae of Lepidoptera, has strong fecundity and environmental adaptability, and it is easy to develop resistance to various types of insecticides. The resistance to formamide and cyantraniliprole develops slowly. However, when such insecticides are used for seed treatment, the effect is ...
