Abstract

The invention discloses a bactericidal composition containing azoxystrobin, a pesticide with the composition, and application of the composition. The bactericidal composition is composed of azoxystrobin and cuppric nonyl phenolsulfonate at the mass ratio of 1:20 to 20:1 and at the preferable ratio of 1:10 to 10:1. The composition is an effective ingredient and can be combined with acceptable auxiliary ingredients in the pesticide to form the corresponding bactericidal pesticide. Experiments prove that after being compounded, the azoxystrobin and the cuppric nonyl phenolsulfonate can generate a remarkable synergistic effect in the prevention and cure of fruit and vegetable crop diseases such as cucumber downy mildew, bacterial angular leaf spot or cucumber blight, the resistance to drugs can be delayed, the amount of single dosage is reduced, the cost is lowered, and the applicable range can be expanded.

Description

technical field [0001] The invention relates to a bactericidal composition, specifically a bactericidal composition composed of azoxystrobin and nonyl copper, as well as the corresponding bactericidal pesticide and its application in the prevention and control of crop diseases such as fruits / vegetables. Background technique [0002] Cucumber downy mildew is caused by Pseudomonas cuba ( Pseudoperonosporacubensis ) caused by the disease. Due to changes in farmland ecosystems and increased resistance to plant diseases, the damage of cucumber downy mildew has become more serious in recent years, and it has occurred continuously throughout the country. It has become a serious disease that has caused great losses to cucumbers. [0003] Cucumber bacterial angular spot is one of the important diseases on cucumber. It often occurs mixed with cucumber downy mildew in the field, and mainly damages leaves, petioles, tendrils and fruits, and can be damaged from seedling to adult plant...
