Embodiment 1

[0048] Example 1: 42% triflumoxystrobin triflustrostrobin suspoemulsion (active ingredient ratio 20:1)

[0049] Weigh 40% Tefluconazole original drug, 2% Trifloxystrobin original drug, 3% FS3000 (phosphate ester type anionic surfactant), 1% SXC (sulfonic acid type anionic surfactant), 30% solvent oil S150 , 5% Nongru 500, 1% NS-500LQ, 0.1% xanthan gum, 5% ethylene glycol, 0.03% BIT (1,2-benzisothiazolin-3-one), 0.3% organic modified silicon Oxane defoamer, deionized water added to 100%.

[0050] First, mix trifloxystrobin technical material, FS3000, SXC, ethylene glycol, defoaming agent, and part of deionized water evenly, and sand-grind trifloxystrobin in a sand mill to obtain trifloxystrobin suspension mother liquor. Then dissolve and mix the original drug of tetraflumezazole, solvent oil, and emulsifier evenly to obtain a uniform oil phase. Water is added to the suspended mother liquor and mixed and sheared evenly. Then add the thickener xanthan gum and the preservative ...

Abstract

The invention relates to a sterilization composition containing tetraconazole and trifloxystrobin according to the weight ratio being 100:1-1:100, and particularly 20:1-1:20. Compared with single sterilization agents, the sterilization composition has the advantages that the obvious synergy effect is realized on the rice sheath blight disease, the rice blast and the false smut, the sterilization effect is improved, the effect is obviously higher than that obtained when the single sterilization agent is singly used, in addition, the medication cost is low, the environment pollution and the pesticide residue are reduced, the acting sites are increased, and the germ medicine resistance generation is favorably overcome. The sterilization composition does not have adverse influence on test crops, the leaf color, the growth condition and the like are normal, the safety is good, and the sterilization composition conforms to the pesticide preparation safety requirements.

Description

technical field [0001] The invention relates to an agricultural composition and an agricultural fungicide, in particular to an agricultural composition and an agricultural fungicide for preventing and treating rice sheath blight, rice smut and rice blast. Background technique [0002] Rice sheath blight, rice false smut and rice blast are important diseases of rice and are the three major diseases of rice production in my country, which occur in all rice-producing areas of the country. [0003] Rice sheath blight is an important disease in rice production areas, and it is one of the three major diseases of rice in my country. It occurs in all rice production areas in the country, and it occurs more frequently in the Yangtze River Basin and southern rice areas. Occurrence is the most common and serious. It is mainly caused by Rhizoctonia solani, a fungus subphylum, and the disease spreads from bottom to top. When it is severe, it can affect the flag leaves and even the ears, ...
