example 1

[0019] Bioassay Example 1: Indoor Toxicity Determination of Rice Blastamide and Kasugamycin Compound to Rice Magnaporthe grisea

[0020] Test object: rice blast fungus collected from the field

[0021] 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 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 1×10 5 spores / mL suspension was evenly sprayed and inoculated on the test rice seedlings, and after inoculation, they were covered with black plastic bags to keep moisture and cultivated for 24 hours. 24 hours after inoculation, carry out medicament treatment, set 5 concentration gradients for each medicament, and spray at 50PSI pressure with a Potter spray tower, about 5mL...

[0033] Bioassay Example 2: Indoor Toxicity Determination of Rice Blasticamide and Polyoxin Compound to Rice Sheath Blight

[0034] Test object: Rice sheath blight fungus collected from the field

[0035] Test method: refer to "People's Republic of China Agricultural Industry Standard NY / T1154.7-2006", broad bean detached leaf method. Rice sheath blight fungus is cultivated with PDA medium. When the bacterial colony is just full of the petri dish, a puncher with an inner diameter of 5 mm is used to punch holes from the edge, and the resulting mycelium block is used as an inoculum. Select broad bean leaves with the same leaf position, 10 leaves for each treatment, soak in the prepared medicinal solution for 10 minutes, take them out to dry, and put them into a petri dish covered with moisturizing paper. Five concentration gradients were set for each drug. Finally, the mycelium block was placed upside down and connected to the center of the leaf, and cultivated in a constant te...

Abstract

The invention relates to a sterilization composition; the effective components are fenoxanil (A) and an antibiotic (B) selected from kasugamycin, polyoxin, and the like, wherein the mass ratio of A toB is 30: 1 to 1: 50; and the composition further contains acceptable supplementary components permitted to be used in pesticide. The sterilization composition of the invention can be prepared into any one preparation formulation for agriculture by the known method; the favorable formulations are as follows: wettable powder, suspending agent, water dispersible granule, aqueous emulsion and micro emulsion. After being compounded with the selected antibiotic, the composition has obvious synergy and is mainly used for preventing and treating rice diseases.

Description

technical field [0001] The invention relates to a bactericidal composition, especially a compound bactericidal composition containing blastamide and antibiotics. Background technique [0002] Rice is one of the main food crops in my country. Its planting area accounts for about 1 / 4 of the country's cultivated land area, and its annual output accounts for about 1 / 2 of the country's total grain output. 40%. Rice blast and sheath blight are important diseases of rice with large occurrence area, high prevalence and serious damage. With the long-term use of conventional pesticides such as tricyclazole, rice blastazim, and carbendazim, the resistance of rice blast fungus and sheath blight fungus has become more and more serious, and the control effect has declined. Due to the enhanced resistance of pathogens, it leads to frequent application of pesticides and increases the burden on farmers and environmental pollution. Therefore, there is an urgent need for efficient, safe and e...
