[0031] Biological Assay Example 1: Indoor Toxicity Determination of Compositions to Cucurbit Downy Mildew

[0032] The test object is cucumber downy mildew (Pseudoperonospora cubensis).

[0033] Test method: refer to "People's Republic of China Agricultural Industry Standard NY / T1156.11-2008". Two cucumber seedlings at the true leaf stage were selected in pots with the same growth potential, and 5 pots were selected for each treatment, and the numbers were reserved for future use. Spray with a Potter spray tower at a pressure of 50PSI, 5mL per pot. For the test treatments, see Table 1, Table 2, and Table 3, and 5 concentration gradients were set for each drug. After 24 hours, the inoculation concentration was 3×10 5 sporangia / mL of cucumber downy mildew sporangia suspension. The cucumber seedlings sprayed with the same amount of water were used as the blank control. After inoculation, the cucumber seedlings were cultured in a light-humidity box. After 10 days, the diseas...

Abstract

The invention discloses a bactericidal composite. The bactericidal composite consists of fluazinam (A) and propamocarb (B) which are active ingredients, wherein the weight ratio of the ingredient A to the ingredient B is (1:80)-(80:1). The composite has obvious synergy and high control effect and is suitable to prevent and treat various diseases and infections of fruits and vegetables, in particular to prevent and treat downy mildew.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a bactericidal composition containing fluazinam. Background technique [0002] Downy mildew is a plant disease caused by downy mildew in fungi. Common downy mildews include melon downy mildew, grape downy mildew, tobacco downy mildew, lettuce downy mildew, soybean downy mildew, sugarcane downy mildew, litchi downy mildew, etc. [0003] The disease can occur at all stages from seedlings to harvest, and the adult plants suffer the most. It mainly damages the leaves and develops from the base to the upper leaves. Field planting is too dense, watering too early after planting, too large, high soil moisture, poor drainage, etc. are prone to disease. Continuous rainy weather in late spring, early summer or autumn is most likely to occur, and when the disease is severe, it can cause 30% to 70% yield loss. [0004] Fluazinam is a 2,6-dinitroaniline compound, which is a broad-spectrum pro...
