[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. See Table 1 and Table 2 for test treatments, 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 disease index was inv...

Abstract

The invention discloses sterilizing combination. The combination comprises the following effective constituents: mandipropamid (A) and cyazofamid (B), with the mass ratio of 1:60 to 60:1. The combination has obvious synergistic effect and high control effect, is suitable for controlling various diseases on fruits and vegetables, and is particularly suitable for controlling downy mildew.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a bactericidal composition containing mandipropamid. Background technique [0002] Downy mildew is a plant disease caused by Oomycete downy mildew in fungi. Common downy mildews include melon downy mildew, lettuce 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 seedling to harvest, and it is most likely to occur in continuous rainy weather in late spring, early summer or autumn. When the disease is severe, it can cause 30% to 70% yield loss. [0004] Mandipropamid is an amide fungicide. Its mechanism of action is to inhibit the biosynthesis of phospholipids, and it has a good control effect on most leaf and fruit diseases caused by oomycetes. It has high activity on spores in the germination stage, and can inhibit mycelial growth a...
