Embodiment 2

[0036] 2. Example 2: 32% compound of formula 1·fludioxonil water dispersible granules (15:1)

[0037]

[0038]

[0039] The preparation method of the water dispersible granules is as follows: according to the above formula, the compound of formula 1, fludioxonil, dispersant, wetting agent, disintegrant and filler are mixed uniformly, pulverized with an ultrafine jet mill, kneaded, and then It enters into an extrusion granulator for granulation, is dried in a boiling dryer, and is sieved and analyzed by sampling to obtain the water dispersible granules of the present invention.

Abstract

The invention relates to a nematicide composition containing fludioxonil. Active ingredients of the nematicide composition comprise a compound as shown in formula 1 and the fludioxonil, and the weightratio of the compound as shown in formula 1 to the fludioxonil is 40: 1-1: 1, and is 15: 1-5: 1 preferably. Prevention and control of the active ingredients of the nematicide composition to various crop root knot nematode diseases in the ratio range have obvious synergistic interaction effects, and the nematicide composition containing the fludioxonil is particularly suitable for various nematodes such as wheat root-knot nematode and heterodera glycines Ichinohe, orange root-knot nematode, cucumber root-knot nematode, tomato root-knot nematode, chili root-knot nematode, peanut root-knot nematode and soybean heterodera glycines Ichinohe. The nematicide composition containing the fludioxonil is good in prevention and control effect, long in lasting period and worthy of being popularized andused.

Description

Technical field [0001] The invention belongs to the field of pesticide nematicidal, and specifically relates to a nematicidal composition of fludioxonil and 1,3,4-oxadiazole sulfide compounds. Background technique [0002] Plant nematode diseases are plant diseases caused by the invasion and parasitism of plant parasitic nematodes. Damaged plants can affect normal growth and development due to invading nematodes to absorb nutrients in the body; the secretions in the process of nematode metabolism can also stimulate the cells and tissues of the host plant, leading to 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 nematode disease, Citrus semi-piercing nematode disease and so on. [0003] It is k...
