Problems solved by technology

However, it is relatively expensive to use alone, and the types of diseases that can be controlled are not enough.
[0004] The bactericidal mechanism of triazole fungicides is relatively complex, mainly inhibiting the biosynthesis of ergosterol in the bacteria, thereby inhibiting or interfering with the development of the bact...

[0018] Bioassay example 1 Toxicity determination of cyprodinil (A) and a triazole fungicide (B) compounded against cucumber powdery mildew

[0019] Test object: Cucumber powdery mildew

[0020] 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" This test uses the cucumber powdery mildew pot test method. On the basis of the preliminary test, select 2 melon seedlings at the true leaf stage with the same growth, write the label number with an oily marker, insert it into the pot of cucumber seedlings, discharge them in sequence, and spray the medicine on the melons by spraying the leaves. On the leaves of seedlings, after spraying treatment, dry the test materials in the fume hood or greenhouse for 24 hours before inoculation. Cultivate in the greenhouse for 7 days to investigate the control effect, the grading standard implements the nati...

[0033] Biological Assay Example 2: Cyprodinil (A) and a triazole fungicide (B) combined toxicity assay for rice blast

[0034] Test object: rice blast fungus

[0035] 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". There were five replicates for each concentration, and a total of 10 rice plants were divided into 5 pots for each treatment. Water treatment was used as blank control. Wash the surface spores of the cultivated pathogenic bacteria with sterile water, and make 1×10 6 spores / ml spore suspension, at the three-leaf stage of rice, use a crop sprayer to inoculate on the rice leaves and evenly spray the inoculation. After 24 hours of darkness, moisturize and remove after 10 days. The number of diseased spots on each rice leaf (30 leaves in total) was counted, and graded according to the number of leaf diseased spots. Calcul...

[0055] Biological assay example 3: Toxicity determination of cyprodinil (A) and a triazole fungicide (B) compounded against Botrytis cinerea

[0056] Test object: Botrytis cinerea of ​​cucumber, Botrytis cinerea of ​​tomato

[0057] 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" using the growth rate method (plate method). On the basis of the preliminary test, on the aseptic operation table, quantitatively add the pre-thawed sterilized medium into the sterile Erlenmeyer flask according to the test treatment. Have 45ml of heat medium (PDA medium, 45-50 ℃) in the Erlenmeyer flask, after shaking well, pour into the glass petri dish of diameter 90mm rapidly, each petri dish is poured into 10ml of culture medium with medicine. Set aside horizontally to cool and form into slabs. Each concentration was replicated five times. The treatmen...

Abstract

The invention discloses a sterilization composite. The active components thereof is cyprodinil (A) and triazole fungicide (B), B is difenoconazole, hexaconazole, propiconazole, flusilazole, penconazole, triazolone, diniconazole, triflumizole or flutriafol; the mass ratio of (A) and (B) is 50-1:1-50. The active components (A) and (B) have obvious synergized effect after compounding in curing and preventing diseases, especially fungal diseases, of crops of fruit tree, cotton, rice, vegetable and the like.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a bactericidal composition containing cyprodinil. 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, gray mold, powdery mildew, scab, and surplus blight, which have become one of the main methods of chemical control. big problem. 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] Cyprodinil, English common name Cyprodinil, chemical name 4-cyclopropyl-6-methyl-N-phenylpyrimidin-2-amine, is a protective fungicide, the mechanism of action is methionine biosynthesis inhibitor, Acts after spore germination, inhibits fungal penetration process a...
