example 1

[0020] Bioassay example 1: Pot test of rice blastamide combined with allylbenthiazole or tetrachlorophthalide on rice blast fungus

[0021] Test object: rice blast fungus (collected from the field and separated and purified)

[0022] Test method: potted plant method. Select rice seedlings at the three-leaf-one-heart stage with consistent growth, 2 seedlings per pot, and 5 pots 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 of the spore suspension was evenly sprayed and inoculated on the test rice seedlings, and after the inoculation, they were covered with black plastic bags for moisturizing cultivation (25°C). After 24 hours of inoculation, medicament treatment was carried out, and 5 concentration gradients were set for each medicament, and sprayed with a Potter spray tower at a pressure of 50 PSI, 5 mL per treatment. After spraying, t...

Abstract

The invention provides a pesticide composition containing one of fenoxanil as effective ingredient, probenazole as plant immunoactivator and rabcide as protective bactericide, as well as the rest auxiliary ingredients which are allowed and acceptable in pesticide and, wherein the mass percent of the effective ingredient in the composition is 5%-80%. The pesticide composition according to the invention is mainly used for the prevention and the treatment of paddy rice diseases, and is favorably effective to rice blast especially.

Description

technical field [0001] The invention belongs to the technical field of pesticide compounding, and relates to a pesticide composition, in particular to a compound pesticide composition containing blastamide, plant immune activator allylbenzothiazole or protective fungicide tetrachlorophthalide. Background technique [0002] Rice blast has a large area of ​​occurrence, high prevalence, and serious damage. It is one of the important diseases of rice, and it is also an epidemic disease that spreads through air currents. It poses a great threat to rice production and seriously affects the yield and quality of rice. In recent years, due to the long-term single use of conventional pesticides such as rice blastin and tricyclazole, the resistance of rice blast fungus has become more and more serious, and the control effect has declined, which has become a major problem in chemical control. [0003] Fenoxanil (Fenoxanil) is a new type of high-efficiency amide fungicide with good syste...
