Problems solved by technology

DCJW can inhibit the voltage-gated sodium channel of insect nerve cells and block the conduction of nerve impulses in insects, thereby inhibiting the transmission of nerve impulses in insects, paralyzing the feeding organs of insects, making them unable to eat, and finally causing the whole body of insects to become stiff due to no energy supply and die
[0004] In the actual process of agricultural production, the application of chemical agents is the most effective means of controlling plant diseases and insect pests, but the most likely problem caused by chemical control of pests is the emergence of pest resistance

Embodiment 1

[0036] Embodiment 1: (40% pyrimethanil · indoxacarb wettable powder)

[0037] An insecticide composition, comprising 26.6% of pyrimethanil, 13.3% of indoxacarb, 5% of wetting agent sodium lauryl sulfate, 8% of calcium lignosulfonate, and 15% of white carbon black by weight percentage , The balance is kaolin.

[0038] The preparation method of Example 1: According to the above formula ratio, the active ingredients pyrimethanil and indoxacarb were added to the kaolin, and then the wetting agents sodium lauryl sulfate, calcium lignosulfonate, and white carbon black were added, mixed, Grinding by jet to D 90 Less than 20μm, and then mixed to make wettable powder.

Embodiment 2

[0039] Embodiment 2: (25% pyrimethanil · indoxacarb aqueous suspension concentrate)

[0040] An insecticide composition, comprising 12.5% ​​pyrimethanil, 12.5% ​​indoxacarb, 2% octylphenol polyoxyethylene ether phosphate, 6% polycarboxylate, 0.1% xanthan gum, 1% magnesium aluminum silicate, 5% ethylene glycol, 0.2% silicone compound, and the balance is water.

Embodiment 3

[0041] Embodiment 3: (30% indoxacarb · pyrimethanil water suspension concentrate)

[0042] An insecticide composition, comprising 10% pyrimethanil, 20% indoxacarb, 2% octylphenol polyoxyethylene ether phosphate, 5% polycarboxylate, 0.15% xanthan gum, silicon 1.5% magnesium aluminum acid, 5% ethylene glycol, 0.1% silicone compound, and the balance is water.

[0043] The preparation method of Examples 2 and 3: according to the above formula ratio, the active ingredients pyrimethanil and indoxacarb, octylphenol polyoxyethylene ether phosphate, polycarboxylate, xanthan gum, magnesium aluminum silicate, ethyl Diols and silicone compounds are placed in the reaction kettle in turn, mixed with water, sheared at a speed of 3000rpm for 10-15min, and wet sanded to D 90 The insecticidal composition is obtained by filtering through a 325-mesh test sieve.

Abstract

The invention belongs to the field of insecticides, and particularly relates to an insecticidal composition containing pyriminostrobin and indoxacarb. The insecticidal composition comprises effectivecomponents including pyriminostrobin and indoxacarb. The beneficial effects are that: 1, indoxacarb is a voltage-gated sodium channel blocking agent in insect nerve cells, and can block nerve impulseconduction in insect bodies; pyriminostrobin is a mitochondrial electron transfer inhibitor, can inhibit the generation of ATP in organisms, indirectly inhibit the transmembrane transport of nerve cell sodium ion channels to ions, indirectly inhibit the nerve impulse transfer of insects, and form a synergistic effect with indoxacarb; the insecticidal composition is composed of effective componentswith different action mechanisms, the number of action sites is increased, generation of insecticide resistance of pests is delayed, and the insecticidal spectrum is expanded; 2, the pesticide effectof the insecticidal composition is obviously improved, the lasting period is prolonged, the field dosage of effective components is reduced, the production and use cost is reduced, and the pollutionof pesticide residues to the environment is reduced.

Description

technical field [0001] The invention belongs to the field of insecticides, and in particular relates to an insecticidal composition comprising pyrimethanil and indoxacarb and a preparation method thereof. Background technique [0002] Flufenerim (flufenerim) is a new type of pyrimidine insecticide introduced by Ube Industries, Japan, and is now being developed by Sumitomo Chemical. It has good control effect on diamondback moth, brown planthopper, black-tailed leafhopper, two-spotted spider mite and incognita root-knot nematode. The mechanism of action is a mitochondrial electron transport inhibitor. [0003] Indoxacarb is a new type of oxadiazine insecticide, which acts on the sodium ion channel in the nerve cells of pests. Indoxacarb is a safe, low-risk, and environmentally friendly insecticide. It is a voltage-gated sodium channel blocker in insect nerve cells and can be decomposed into compounds with higher activity in the insects receiving the drug. Indoxacarb has a ...
