Embodiment 1

[0018] Preparation method example 1: 22% captan · ibuprole · thiazolyl suspension concentrate: active ingredients by weight, 1.5% captan, 0.5% ibuprole, 20% thiazolyl, fatty alcohol polyoxyethylene ether 1%, Nongru 5002%, castor oil polyoxyethylene ether 2%, xanthan gum 0.5%, aluminum magnesium silicate 0.8%, propylene glycol 5%, silicone 3%, the rest is supplemented with water. The above formula is pre-crushed in proportion, then added to a sand mill for grinding, and prepared after high-shear mixing to prepare a 22% captan, ibuprole, and thiazolyl suspension

Embodiment 2

[0019] Preparation method example 2: 60% captan · ibuprole · thiazolyl wettable powder: the following components are weight percent: captan 7%, 3% ibuprole, thiazolyl 50%, pull open powder 2%, naphthalenesulfonate formaldehyde condensate 4%, wood sodium 5%, NNO 4%, and the balance is filler kaolin. The above formula is coarsely pulverized in proportion, put into a mixer and mixed evenly, and then jet pulverized to obtain a 60% captan·bufenapyr·thiazolyl wettable powder.

Embodiment 3

[0020] Preparation method example 3: 15% captan·chlorfenapyr·thiazolyl granules: active ingredients captan 4.8%, 0.2% tetraprole, 10% thiazolyl, sticky powder 5%, lignin Sodium sulfonate 2%, paraffin 3%, reactive red 2%, kaolin to 100%. Add the above materials together into a conical mixer and mix them evenly, then pulverize them through a jet mill, put them into a disc granulator, add water to granulate them, and then dry them through a drying cylinder, sieve them, and cool them down in a cooling cylinder to obtain 15% grams of bacteria Dan·bufenpyr·thiazolyl granules.

Abstract

The invention relates to a pesticide composition containing captan, flufiprole and fosthiazate. Active ingredients of the pesticide composition are captan, flufiprole and fosthiazate. Weight ratio of captan to flufiprole to fosthiazate is 1-40:1-40:50-200, preferably 10-20: 10-20: 80-120. Total weight of captan, flufiprole and fosthiazate is 0.1-50% of weight of the pesticide composition. The pesticide composition can be made into a suspending agent, a wettable powder and granules, and is suitable for controlling crop root diseases, especially cucumber root rot and root-knot nematode. By the use of the pesticide composition, control effect can be enhanced, control range can be broadened, various insect diseases can be controlled by one-time drug application, manpower is saved, and labor cost is reduced.

Description

technical field [0001] The present invention relates to a pesticide composition, in particular to a pesticide composition with captan, chlorfenapyr and thiazolyl as active ingredients, which is used for the prevention and control of crop root diseases and insect pests. Background technique [0002] Plant-parasitic root-knot nematodes mainly include: Meloidogyne, Rotylenchulus, cyst root-knot nematode [Heterodera], root-knot nematode (Pratykenchus), root-knot nematode damage can greatly reduce the absorption of nutrients and water by plants, while root-knot nematodes absorb plant root nutrients, and root-knot nematodes cause wounds to plants, causing root rot root diseases. [0003] Root rot (Wilt) is a soil-borne disease caused by fungi of the subphylum Deuteromycotina. It often occurs after flowering and fruiting. The damaged plant initially shows that some leaves or one side of the plant wilt and droop at noon, as if lack of water. Sooner or later, wilting leaves will co...
