[0034] Biological Assay Example 1: Indoor Toxicity Determination of Compositions to Magnaporthe grisea

[0035] The test object is rice blast fungus (Pyricularia oryzae).

[0036] Test method: refer to "People's Republic of China Agricultural Industry Standard NY / T1154.7-2006", pot method. Select rice seedlings at the three-leaf-one-heart stage with consistent growth potential, 2 seedlings per pot, and 5 pots of rice seedlings for each treatment. The rice blast fungus was cultured on the tomato juice oat agar medium, and after spore production, the spores were washed with sterile water to make 3×10 5The suspension of spores / mL was evenly sprayed and inoculated on the rice seedlings for testing, and after inoculation, it was cultured in a light and moisture incubator for 24 hours in a dark moisture (humidity 100%). 24 hours after inoculation, carry out medicament treatment, set 5 concentration gradients for each medicament, and spray at 50PSI pressure with a Potter spray towe...

Abstract

The invention discloses a bactericide composite, which consists of active ingredients of fluazinam (A) and kasugamycin (B), and the mass ratio of A to B is 1:100 to 100:1. The composite has obvious synergy and high prevention effect, and is suitable for controlling diseases on cereal crops, particularly for controlling rice blast.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a bactericidal composition with fluazinam and kasugamycin as main components. Background technique [0002] Rice blast is one of the three major diseases of rice, also known as rice fever, fire blast, and knocking blast. It occurs in every rice area in China, and mainly damages leaves, stems, and panicles. Because of the time and location of the disease, it can be divided into seedling blast, leaf blast, knot blast, panicle blast, and grain blast. Seedling blast occurs in front of the three leaves and is caused by seed infection. The base of the diseased seedlings is gray and black, and the upper part turns brown, shrinks and dies. When the humidity is high, the diseased part produces a large number of gray and black mold layers, that is, the conidiophores and conidia of the pathogenic bacteria. Leaf blast can occur throughout the growth period. The damage is severe from tillerin...
