Embodiment 1

[0063] 10.2% Boscalid·Benthiazil EC

[0064] The raw material ratio is: boscalid 10%, benthiazil 0.2%, N-pyrrolidone 10%, DMF 10%, Nongru 1601#5%, Nongru 500#5%, xylene supplemented to 100%, According to the conventional production method, it is added into the mixing kettle in sequence according to the formula ratio, and stirred evenly to obtain the emulsifiable concentrate.

[0065] The emulsifiable concentrate prepared in Example 1 is applied to strawberry botrytis. Dilute 10.2% boscalid · benthiazil EC 500 times (the effective concentration of boscalid is 200 μg / ml, the effective concentration of benthiazil is 4 μg / ml) and spray it with water, 7 days and 15 days after the medicine The control effects were 93.6% and 92.1%, respectively. 25% boscalid suspension was used at 1000 times (effective concentration is 250 μg / ml) and 30% benthiazil suspension was used at 1000 times (effective concentration was 250 μg / ml) in the same way, after 7 days and The 15-day control effects...

Embodiment 2

[0067] 5% boscalid · benthiazil microemulsion

[0068] The ratio of raw materials is: boscalid 2.5%, benthiazil 2.5%, xylene 10%, isopropanone 10%, Nongru 1601# 5%, Nongru 500# 5%, water to 100%. Prepare microemulsion according to formula ratio according to conventional production method.

[0069] The microemulsion prepared in Example 2 was applied to botrytis cinerea. Dilute 5% boscalid·benthiazil microemulsion by 200 times (the effective concentration of boscalid is 125 μg / ml, and the effective concentration of benthiazil is 125 μg / ml) and spray it with water. The control effects of days were 97.6% and 96.9%, respectively. 25% boscalid suspension was used at 1000 times (effective concentration is 250 μg / ml) and 30% benthiazil suspension was used at 1000 times (effective concentration was 250 μg / ml) in the same way, after 7 days and The 15-day control effects were 88.9%, 85.7%, 86.3%, 84.5%, respectively. The results showed that the compounding of boscalid and benthiazil ...

Embodiment 3

[0071] 20% boscalid · benthiazil aqueous emulsion

[0072] The ratio of raw materials is: boscalid 5%, benthiazil 15%, xylene 10%, calcium dodecylbenzene sulfonate 5%, agricultural milk 600# 5%, and water to make up to 100%. According to the routine production method of pesticide preparations, it is prepared into water emulsion according to the formula ratio.

[0073] The emulsion in water prepared in Example 3 was applied to Botrytis cinerea. Dilute and spray 20% boscalid·benthiazil aqueous emulsion 1000 times (the effective concentration of boscalid is 50 μg / ml, and the effective concentration of benthiazil is 150 μg / ml) with water. The control effects of days were 95.6% and 92.8%. 25% boscalid suspension was used at 1000 times (effective concentration is 250 μg / ml) and 30% benthiazil suspension was used at 1000 times (effective concentration was 250 μg / ml) in the same way, after 7 days and The 15-day control effects were 89.7%, 85.9%, 86.2%, 83.7%, respectively. The res...

Abstract

The invention discloses a sterile composition containing boscalid and benthiavalicarb isopropyl. The sterile composition comprises the boscalid and the benthiavalicarb isopropyl as effective ingredients, wherein the weight percent of the effective ingredients in the sterile composition is 5-80%, and the weight percent ratio proportion of the effective ingredients is (50:1)-(1:50), preferably, (20:1)-(1:20). The sterile composition disclosed by the invention achieves obvious synergistic effect after the boscalid and the benthiavalicarb isopropyl are compounded; the field dosage can be reduced greatly, the pesticide residue and environment pollution are reduced, and the production cost and the use cost are reduced; the single selection pressure on pathogenic bacteria is reduced to better prevent the generation of disease resistance and slow the generation speed of disease medicine resistance; and the sterile composition is mainly applied to the prevention and treatment of crops botrytis and downy mildew.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a compound bactericidal composition containing boscalid and benthiazil. Background technique [0002] Botrytis cinerea and downy mildew are common diseases in the planting process of vegetables, flowers and fruits. The damage period is long and the spread is fast. In severe periods, they often cause a substantial reduction in crop production, seriously affecting quality and economic benefits. The development of related control products is of great significance. Huge market space. According to literature reports, due to single drug use and other unscientific drug use methods, botrytis cinerea and downy mildew have developed resistance to commonly used pesticides, and the increase in the amount and frequency of spraying after the resistance has caused farmers a burden The aggravation and environmental pollution are intensified, so the mixing of different pesticide varieties has become...
