preparation Embodiment

[0026] 1. Embodiment 1: 55% compound of formula 1 Cartap water dispersible granules (1:10)

[0027]

[0028]

[0029] The preparation method of the water-dispersible granules is as follows: mix the compound of formula 1, cartap, dispersant, wetting agent, disintegrating agent and filler uniformly according to the above method, pulverize with an ultrafine jet mill, knead, and then Enter the extruding granulator to granulate, dry in the boiling dryer, and after sieving, the water-dispersible granule of the present invention is obtained through sampling and analysis.

Embodiment 2

[0030] 2. Embodiment 2: 12% formula 1 compound · cartap suspension concentrate (1:5)

[0031]

[0032] The specific processing steps of the composition suspending agent are: mix water with wetting agent, dispersant, thickener, antifreeze agent and defoamer according to the above formula, mix uniformly through high-speed shearing, add the compound of formula 1, Cartap, continue to shear and mix, and then enter the horizontal sand mill to grind, so that the particle size of the preparation is all below 5UM, and the suspension concentrate of the present invention is obtained.

[0033] 3. Embodiment 3: 60% formula 1 compound · cartap wettable powder (2:3)

[0034]

[0035] The preparation method of the wettable powder is as follows: mix the compound of formula 1, cartap, dispersant, wetting agent and filler according to the above formula, stir evenly in a stirring tank, and mix evenly after jet crushing to obtain The wettable powder of the present invention.

Abstract

The invention relates to a novel nematicidal composition containing cartap. The nematicidal composition comprises the active components of a compound of a formula 1 and cartap, wherein the weight ratio of the compound of the formula 1 to the cartap is (5-50):(3-45), and furthermore the weight ratio is preferably (20-40):(8-35). Through the nematicidal composition containing the active components in the ratio range, an obvious synergistic effect on control of root-knot nematode of multiple crops is achieved, and the nematicidal composition is particularly suitable for control of root-knot nematode and cyst nematode of wheat, citrus root-knot nematode, cucumber root-knot nematode, tomato root-knot nematode, capsicum annuum root-knot nematode, peanut root-knot nematode, soybean cyst nematodeand other nematode. The nematicidal composition has a good control effect and long duration of efficacy, and is worthy of promotion and application.

Description

technical field [0001] The invention relates to a nematocidal composition containing styrene-based 1,3,4-oxadiazole sulfide compounds and cartap and application thereof. Background technique [0002] Plant nematode disease is a plant disease caused by the attack and parasitism of plant parasitic nematodes. Infected plants can affect normal growth and development due to the invading nematodes absorbing nutrients in the body; the secretions of the nematodes in the metabolic process can also stimulate the cells and tissues of the host plant, resulting in plant deformities, etc., reducing the yield and quality of agricultural products. The more serious plant nematode diseases in China include root-knot nematode disease of melons, solanaceous fruits, bananas, citrus and other crops, soybean cyst nematode disease, wheat grain nematode disease, sweet potato stem nematode disease, rice stem apical nematode disease, Citrus semipuncturing nematode, etc. [0003] Known, styryl-based ...
