Embodiment 1

[0018] 50% thiamethoxam · tebuconazole wettable powder

[0019]

[0020] According to the requirements of the above formula, the original drug, various additives and fillers are fully mixed, and after being pulverized by an ultrafine pulverizer, the processed product is obtained.

Embodiment 2

[0022] 30% Tebuconazole Tebuconazole Aqueous Suspension Concentrate

[0023]

[0024] According to the requirements of the above formula, the original drug, emulsifier, antifreeze agent, suspending agent, water, etc. are mixed together, and after high-speed stirring, grind twice to form a water suspension with good dispersibility.

Embodiment 3

[0026] 30% thiamethoxam·tebuconazole water dispersible granules

[0027]

[0028]

[0029] Water-dispersible granules are granulated dosage forms that can disintegrate and disperse rapidly in water, and enable the active ingredients to form a high suspension state in water. Water-dispersible granules are environmentally friendly and can minimize environmental pollution from chemical pesticides. The formulation of water-dispersible granules requires high technical requirements, and the processing procedures are relatively complicated. The production process of water-dispersible granules is diverse. At present, spray drying method, boiling drying method, freeze drying method, fluidized bed method and intermeshing extrusion method are commonly used.

Abstract

The present invention relates to a bactericide composition, more specifically to a bactericidal composition of effective components thiamethoxam and tebuconazole, wherein the weight ratio of thiamethoxam and tebuconazole is preferably 1:80-7 :1, more preferably 1:20 to 1:1. The bactericidal composition is suitable for controlling rice sheath blight and rice false smut.

Description

technical field [0001] The invention relates to a fungicidal composition for preventing and treating rice sheath blight and rice smut. More specifically, the present invention relates to a fungicidal composition containing thiamethoxam and tebuconazole and the use of the composition for preventing and treating rice sheath blight and rice false smut. technical background [0002] Rice sheath blight and rice false smut are the main diseases in rice production. The disease is more serious in South China, Central China and East China, and also occurs in North China, Northeast China and Yunnan rice areas, and it is more serious in some areas. The affected areas generally reduce production by 5-10%, and the severe areas reduce production by 50-70%. Rice false smut occurs in all rice-growing regions in my country, and rice false smut can cause yield loss, and more seriously, affect rice quality. [0003] For a long time, the control of rice sheath blight in rice production has ma...
