example 1

[0017] Bioassay Example 1: Toxicity determination of rice blastamide and prochloraz compounded against rice blast

[0018] Test object: rice blast fungus

[0019] (The test refers to "Pesticide Bioassay Technology" (Edited by Chen Nianchun, published by Beijing Agricultural University Press), and "Pesticide Indoor Bioassay Test Guidelines NY / T1156.2-2006". 2 plants, each concentration was repeated five times, and each treatment totaled 10 rice plants, which were divided into 5 pots. Treated with clear water as a blank control. Wash the spores on the lower surface of the cultivated pathogenic bacteria with sterile water, and make 1 × 10 6 For the concentration of spores, at the three-leaf stage of rice, use a crop sprayer to inoculate on the rice leaves and evenly spray the inoculation. After treatment, the rice seedlings were bagged and cultured for 24 hours, then sprayed with pesticides, placed in a greenhouse to keep moisture, and taken out after 10 days. Count the number ...

Embodiment 1

[0028] Embodiment 1: 21% rice blastamide prochloraz suspension concentrate

[0029] Blasticamide 20%

[0030] Prochloraz 1%

[0031] Sodium methylnaphthalenesulfonate formaldehyde condensate 10%

[0032] Xanthan Gum 1%

[0033] Bentonite 1%

[0034] Glycerol 1%

[0035] Water Make up to 100%.

[0036] Active components, dispersant, wetting agent, water and other components are uniformly mixed according to the ratio of the formula, and after grinding and / or high-speed shearing, a 21% rice blastamide prochloraz suspension is obtained.

[0037] This embodiment is applied to the prevention and treatment of rice blast. The 21% blastamide-prochloraz wettable powder was diluted 1000 times with water and sprayed, and the control effects were 94.5% and 91.7% 7 days and 15 days after the application. 20% blastamide suspension concentrate and 5% prochloraz EC were used in the same way at 800 times and 800 times, and the control effects were 90.9%, 74.2%, 89.9%, and 65.6% at 7 days...

Embodiment 2

[0038] Embodiment 2: 20% rice blastamide prochloraz aqueous emulsion

[0039] Blasticamide 15%

[0040] Prochloraz 5%

[0041] N-Methylpyrrolidone 10%

[0042] Calcium dodecylbenzenesulfonate 5%

[0043] Farm Milk 600# 5%

[0044] Water make up to 100%

[0045] Add the original drug, solvent, and emulsifier together to dissolve into a uniform oil phase; mix the water-soluble components with water to obtain a water phase; mix the oil phase with the water phase under high-speed stirring to obtain a 20% rice Pestimid Prochloraz Water Emulsion.

[0046] This embodiment is applied to the control of rice blast. The 20% rice blastamide-prochloraz aqueous emulsion was diluted and sprayed by 1000 times with water, and the control effects were 91.7% and 88.9% respectively 7 days and 15 days after application. 15% blastamide suspension concentrate was used at 800 times and 10% prochloraz EC was used at 800 times by the same method, and the control effects were 88.3%, 70.2%, 85.8%,...

Abstract

The invention relates to a pyricularia amide compound sterilization composition which belongs to a sterilization composition and comprises the effective gradients of pyricularia amide and prochloraz, wherein the mass ratio of the pyricularia amide to the prochloraz is 20: 1-1: 50, and the preferable mass ratio is 5: 1-1: 30. The invention has remarkable synergic effect after the pyricularia amide and the prochloraz are compounded, and is used for preventing and treating diseases, in particular to rice blast of crops, such as fruit trees, cottons, rice, vegetables, and the like.

Description

technical field [0001] The invention relates to a bactericidal composition, especially a bactericidal composition containing blastamide and prochloraz. Background technique [0002] In recent years, due to single and unscientific drug use, many diseases have become resistant to the currently used pesticides, such as rice blast, which has become a major problem in chemical control. In addition, there are many physiological races of rice blast disease, which makes the prevention and control more difficult. At the same time, frequent application of pesticides has caused increased burden on farmers and increased environmental pollution. Therefore, there is an urgent need for new varieties of fungicides with high efficiency, low toxicity and environmental protection. [0003] Blasticamide is a relatively new type of fungicide. It is a novel systemic fungicide jointly developed by Nippon Noroyaku Co., Ltd. and BASF. The period is longer. No cross-resistance with conventional m...
