Embodiment 1

[0045] Example 1: 30% benthiazil·dysenlian suspension concentrate

[0046] Benthiopyram 25%, Disenlian 5%, Naphthalenesulfonate Sodium Formaldehyde Condensate 10%, Aluminum Magnesium Silicate 1%, White Carbon Black 1%, Ethylene Glycol 4%, Water to make up to 100%.

[0047] This embodiment is applied to the control of cucumber downy mildew. Dilute and spray 30% benthiazil·dysenlian suspension 3000 times (the effective concentration of benthiazil is 83.3 μg / ml, and the effective concentration of disenlian is 16.7 μg / ml) with water. Day control effects were 95.5%, 90.2%. 20% benthiazil suspending agent is used in the same way by 2000 times (effective concentration is 100 μg / ml) and 25% disenlian wettable powder is used in the same way (effective concentration is 250 μg / ml), after 7 days and The 15-day control effects were 84.9%, 80.5%, 74.4%, 70.3%, respectively. The synergistic effect of the combination of benthiazil and disenlian is obvious, and the control effect on cucumbe...

Embodiment 2

[0048]Embodiment 2: 3% benthiazil·dysenlian suspension concentrate

[0049] Benthiopyram 0.5%, Disenlian 2.5%, Naphthalenesulfonate Sodium Formaldehyde Condensate 10%, Aluminum Magnesium Silicate 1%, White Carbon Black 1%, Ethylene Glycol 4%, Water to make up to 100%.

Abstract

The invention relates to a sterilization composition which comprises the effective components of benthiavalicarb-isopropyl (A) and polyram (B), wherein the mass ratio of the benthiavalicarb-isopropyl (A) to the polyram (B) is (50:1)-(1:50). After the benthiavalicarb-isopropyl (A) is compounded with the polyram (B), obvious synergism is realized, and the compounded sterilization composition is used for oomycetes disease control of crops such as fruit trees, flowers and plants, cotton, wheat and vegetables.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a compound bactericidal composition containing benthiazil. Background technique [0002] Oomycete diseases such as downy mildew and blight are very important diseases of crops, often causing heavy losses of crops. According to literature reports, due to monotherapy and other unscientific drug use methods, many downy mildews and blights have developed resistance to commonly used pesticides, and the field control effect of pesticides has dropped significantly. After the emergence of resistance, the increase in the amount of pesticide application and the frequency of pesticide application will increase the burden on farmers and aggravate environmental pollution. New fungicides with high efficiency, low toxicity, environmental protection and no cross-resistance and their compositions are one of the ways to solve this problem. [0003] Benthiopyram, chemical name: ((S)-1-((R)-1-(6-fluor...
