[0044] Biological Assay Example 1: Indoor Toxicity Determination of Compositions against Cucurbit Powdery Mildew

[0045] The test object is cucumber powdery mildew (Sphaerotheca fuliginea).

[0046] 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 to Table 6 for test treatments, and 5 concentration gradients were set for each drug. After 24 hours, the inoculation concentration was 3×105 spores / mL of Cucumber powdery mildew conidia 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 the greenhouse. After 10 days, the disease index was investigat...

Abstract

The invention discloses a pesticide composition containing a diaryl ketone compound, which consists of, as effective components, (A) Pyriofenone and (B) ethirimol or ethirimol sulfonate or dimethirimol. The weight ratio of A to B is 1:50 to 50:1. The pesticide composition has obvious synergism and high control effect, is suitable for controlling various diseases and pests in fruits and vegetables, and is particularly suitable for controlling powdery mildew.

Description

technical field [0001] The present invention relates to a bactericidal composition, in particular to a bactericidal composition with diaryl ketone compound and pyrimol or pyrimol sulfonate or pyrimol as main components and its application. Background technique [0002] Powdery mildew is a plant disease caused by fungi of the family Erysiphacesae. For example: cereal powdery mildew caused by Erysiphe graminis; powdery mildew of melons, beans, hemp and other plants caused by Sphaerotheca fuliginea; Powdery mildew of grapes caused by Uncinula necator; powdery mildew of more than 80 kinds of trees such as mulberry, pear, persimmon, walnut, chestnut, litchi and papaya caused by Phyllactinia corylea; monofilament of rose Powdery mildew of Rosa flowers caused by Sphaerotheca pannosa. [0003] In the prevention and control of powdery mildew, fungicides such as benzimidazoles, triazoles, and methoxyacrylates are currently mainly relied on. Due to the long-term use of these agents,...
