example 1

[0018] Bioassay Example 1: Indoor Toxicity Determination of Prothioconazole and Polyoxin to Cucumber Powdery Mildew

[0019] Test object: Cucumber powdery mildew (Sphaerotheca fulignea), collected from the field, cultivated in an artificial climate chamber.

[0020] Test method: refer to the "Agricultural Industry Standards of the People's Republic of China" (indoor bioassay test guidelines for pesticides and fungicides NY / T1156.11-2008 and NY / T1156.6-2006), and adopt the pot method.

[0021] Choose cucumber seedlings with 2 complete true leaves and consistent growth, and cut off the growth point. Each treatment of 5 pots of cucumber seedlings, repeated 5 times. Write the label number with a marker pen, insert it into the potted seedlings, and arrange them in sequence for testing. After spraying for 24h, inoculate the conidia suspension of Cucumber powdery mildew (spore concentration 1×10 5 spores / ml). After inoculation, the test materials were moved to the greenhouse at a...

[0031] Bioassay Example 2: Indoor Toxicity Test of Prothioconazole and Polyoxin to Rice Sheath Blight

[0032] Test object: rice sheath blight (Rhizoctonia solani Kuhn), which was collected in the field, isolated in the laboratory, and reintroduced three times.

[0033] Test method: refer to "Pesticide Indoor Bioassay Test Guidelines NY / T1156.2-2006 and NY / T1156.6-2006", 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. There is 45ml of hot medium (PDA medium, 45-50 ℃) in the Erlenmeyer flask. After shaking well, pour it into a glass culture dish with a diameter of 90mm quickly, and pour 10ml of the medium with medicine into each culture dish. Set aside horizontally to cool and form into slabs. Each concentration was replicated five times. The treatment without drug was used as blank control. ...

Abstract

The invention discloses an agricultural sterilization composition, which comprises effective ingredients of prothioconazole and polyoxins at a weight ratio of (50:1)-(1:50), and the balance of auxiliary ingredients which are allowed for being used in a pesticide and can be accepted. The sterilization composition disclosed by the invention can be prepared into an emulsion in water, a suspension, a microcapsule suspension, missible oil, wettable powder, seed treatment dispersable powder, granules, water aqua or water dispersible granules by adopting a known method. The prothioconazole and the polyoxins are compound in a certain proportion, thus the agricultural sterilization composition has a remarkable synergism, and is mainly used for preventing and controlling cucumber powdery mildew and rice sheath blight.

Description

technical field [0001] The invention belongs to the technical field of pesticide compounding, and relates to an agricultural bactericidal composition, in particular to an agricultural bactericidal composition containing prothioconazole and its application for preventing and controlling crop diseases. Background technique [0002] Prothioconazole, English common name: prothioconazole, molecular formula: C 14 h 15 Cl 2 N 3 OS, a triazolethione fungicide developed by Bayer CropScience, is an ergosterol biosynthesis inhibitor. It has strong systemic, protective, therapeutic and eradicating activities, and has a long-lasting effect and a wide bactericidal spectrum. It is mainly used to prevent and control many diseases on cereals, wheat, beans, sugar beets and field vegetable crops. [0003] At present, chemical control is the key measure to prevent and control plant diseases and insect pests. It is even the only effective measure when faced with the emergency of diseases, in...
