Embodiment 1

[0105] Example 1 8% tetrafluconazole + 15% kysstrobin wettable powder

[0106]

[0107] Mix tetrafluconazole, kresoxim-methyl, dispersant, wetting agent, disintegrating agent and filler according to the proportion of the formula and mix them evenly, and then get the wettable powder of 8% tetrafluconazole + 15% kresoxim-methyl through jet milling .

Embodiment 2

[0108] Example 2 8% Tefluconazole + 15% Kresoxim-methyl Water Dispersible Granules

[0109]

[0110]

[0111] After mixing the above raw materials, a certain amount of water is added, mixed and extruded to make a material, and after drying and sieving, a water-dispersible granule of 8% tetrafluconazole+15% kresoxim-methyl is obtained.

Embodiment 3

[0112] Example 3 8% Tefluconazole + 15% Kresoxim-methyl EC

[0113]

[0114] The above ingredients were prepared according to the proportion, stirred evenly to obtain a homogeneous phase, and an emulsifiable concentrate of 8% tetrafluconazole + 15% azoxystrobin was obtained.

Abstract

The invention relates to a bactericidal composition containing kresoxim-methyl and tetraconazole, and applications of the bactericidal composition in reducing or preventing wheat from being infected by toxins formed by gramineous blumeria graminis wheat specialized fungi. When kresoxim-methyl and tetraconazole exist in the bactericidal composition according to a specific weight ratio, the composition has an especially obvious synergistic effect of reducing or preventing wheat from being infected by toxins formed by gramineous blumeria graminis wheat specialized fungi.

Description

Technical field [0001] The present invention relates to the technical field of pesticide chemistry, and in particular to a fungicidal composition containing acetostrobin and tetrafluoropropazole and its use in crop protection. Background technique [0002] Wheat powdery mildew is a disease caused by fungi, and its pathogenic bacteria is a specialized type of Erysiphe graminis DC. Wheat and barley powdery mildew are different specialized types; the pathogen of wheat powdery mildew is Erysiphegraminis DC.f.sp.tritici Marchal; the pathogen of barley powdery mildew is Erysiphe gramminisDC.f.sp.hordei Marchal. Generally, wheat powdery mildew bacteria do not infect barley, and barley powdery mildew bacteria do not infect wheat. Wheat powdery mildew causes even more serious damage to wheat crops. Plants infected by wheat powdery mildew will be short and weak, unable to head or have short ears. After the plant is damaged, nutrients are robbed, respiration increases, transpiration...
