Embodiment 1

[0025] Embodiment 1: Indoor active formulation determination:

[0026] 1. Test object: Fusarium moniliforme.

[0027] 2. Test method: refer to "Pesticide Bioassay Test Guidelines NY / T1156.2-2006", and use the drug-containing medium method.

[0028] 3. Data analysis: use DPS3.0 software for analysis. Calculate mycelia growth inhibition rate (%) according to test data, obtain toxicity regression equation, EC 50 value and co-toxicity coefficient (CTC).

[0029] 4. Evaluation method: Refer to "Pesticide Bioassay Test Guidelines NY / T1156.2-2006", and evaluate the synergistic effect of pesticide mixture according to the co-toxicity coefficient (CTC) of Sun Yunpei's method (1960). CTC≤80 means antagonistic effect; CTC≥120 means synergistic effect; 80<CTC<120 means additive effect.

[0030] 5. Results and analysis:

Embodiment 2

[0038] Example 2: 5% tebuconazole · fludioxonil · cartap suspension seed coating

[0039] Weigh 2.5 g of fludioxonil technical material (calculated in percent, the same below), 0.5 g of tebuconazole technical material, and 2 g of cartap technical drug, add the technical material to water, stir in a stirring tank until it becomes a homogeneous liquid, add dispersing Agent (sodium lignosulfonate) 0.5% ~ 10%, wetting agent (alkyl naphthalene sulfonate) 0.5% ~ 10%, film forming agent (polyvinyl acetate) 4%, after stirring evenly; at 60 ~ 120rpm Slowly add 0.1% to 5% thickener (polyvinyl alcohol) diluted with water, 1% warning color (basic rhodamine), 0.1% to 5% antifreeze (ethylene glycol) under mechanical stirring, and defoam Agent (silicone oil) 0.01% ~ 3%, make up to 100ml with water, use air compression pipeline to transport material liquid during grinding, and use 4 sand mills in series (filling fine zirconia beads and coarse zirconia beads) for continuous sand grinding , ma...

Embodiment 3

[0041] Embodiment 3: 15% tebuconazole · fluazinam · cartap microemulsion

[0042] Weigh 5g of tebuconazole original drug, 5g of fluazinam original drug, 5g of cartap original drug, add 5% to 25% of organic solvent, 5% to 25% of emulsifier, 0.1% to 5% of antifreeze, and make up to 100ml with water , to make 15% tebuconazole · fluazinam · cartap ME;

[0043] In the above-mentioned microemulsion trial production, the organic solvent is 150# mineral spirits, the emulsifier is fatty acid polyoxyethylene ether series mixture, and the antifreeze agent is ethylene glycol. Fludioxonil is added into the organic solvent under the condition of stirring, then a co-solvent is added, and after the original drug is completely dissolved, an emulsifier is added and the emulsifier is dissolved. Add water and antifreeze under the condition of 50-90rpm / min, add cartap original drug, and stir for 30 minutes to obtain a uniform and transparent microemulsion.

[0044] Replace fluazinam with fludiox...

Abstract

The invention relates to two kinds of rice seed treating agents combined with insecticide and bactericide, and application of the combined rice seed treating agents. The effective components of the combined rice seed treating agent of one kind comprise tebuconazole, fluazinam and cartap, wherein the mass ratio of the tebuconazole to the fluazinam to the cartap is (1-40): (1-40): (1-40) and is preferably (1-3): (1-5): (1-6). The effective components of the combined rice seed treating agent of the other kind comprise tebuconazole, fludioxonil and cartap, wherein the mass ratio of the tebuconazole to the fludioxonil to the cartap is (1-30): (1-30): (1-30) and is preferably (1-2): (1-2): (1-5). To calculate by mass percentage, the total content of the effective components, i.e. the tebuconazole, the fluazinam or the fludioxonil and the cartap in a preparation is 1-90 percent. By adding conventional additives into the effective components of the two kinds of combined rice seed treating agents, agricultural commonly-used preparations can be processed. The combined rice seed treating agents provided by the invention can effectively prevent and control rice seed-borne diseases such as Fusarium moniliforme Sheld and Aphelenchoides besseyi, and soil-borne diseases such as rice blight and pythium rot by adopting a seed coating method, a seed immersing method, a seed dressing method and a seed bud treatment method.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a seed treatment agent which combines tebuconazole, fludioxonil, fluazinam and cartap and is specially used for preventing and treating rice seed-borne diseases and soil-borne diseases. Background technique [0002] Since the 1990s, rice seed-borne diseases have become a prominent problem in production, and rice bakanae disease, rice stem nematode disease, rice blast, rice streak disease, etc. have become frequent diseases. These diseases are all transmitted by seeds, and the best way to prevent and control these diseases is to use seed treatment (seed coating, medicament soaking, etc.). [0003] At present, there are many kinds of medicaments used for rice seed treatment in production, mainly carbendazim, prochloraz, cyclostrobin, etc. are used to kill pathogenic fungi stored in rice seeds to prevent and control rice bakanae disease, rice seedling disease, etc. Plague and othe...
