Embodiment 1

[0018] Embodiment 1: 2.5% rhypronil·cartap suspension seed coating

[0019] Weigh 0.5 g of the original drug of fludioxonil and 2 g of the original drug of cartap, add the two original drugs into water, stir in a stirring tank to a homogeneous liquid, add 0.5% to 10% of a dispersant (sodium lignosulfonate), and moisten Agent (alkyl naphthalene sulfonate) 0.5% ~ 10%, film forming agent (polyvinyl acetate) 4%, after stirring evenly; under 60 ~ 120rpm / min mechanical stirring, slowly add the thickener ( Polyvinyl alcohol) 0.1%~5%, warning color (basic rhodamine) 1%, antifreeze agent (ethylene glycol) 0.1%~5%, defoamer (silicone oil) 0.01%~3%, make up to 100ml with water, When grinding, the air compressed pipeline is used to transport the material liquid, and 4 sets of sand mills connected in series (filled with fine zirconia beads and coarse zirconia beads) are used for continuous sand grinding to make 2.5% fludioxonil·cartap suspension seed coat agent (FS).

Embodiment 2

[0020] Embodiment 2: 5% fludioxonil · cartap microemulsion

[0021] Weigh 2.5g of fludioxonil and 2.5g of cartap, add 5% to 25% of organic solvent, 5% to 25% of emulsifier, 0.1% to 5% of antifreeze, make up to 100ml with water, and make 5 % Fludioxonil Cartap ME;

[0022] 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.

Embodiment 3

[0023] Embodiment 3: 15% fludioxonil · cartap suspension concentrate

[0024] Weigh 5 g of fludioxonil technical material and 10 g of cartap technical drug, add the two technical medicines into water, stir in a stirring tank to a homogeneous liquid, add dispersant (sodium lignosulfonate) 0.5% to 10%, wetting agent (Alkyl naphthalene sulfonate) 0.5% ~ 10%, after stirring evenly; under mechanical stirring at 60 ~ 120rpm / min, slowly add thickener (polyvinyl alcohol) 0.1% ~ 5% diluted with water, antifreeze ( Ethylene glycol) 0.1% to 5%, defoamer (silicone oil) 0.01% to 3%, make up to 100ml with water, use air compression pipeline to transport material liquid during grinding, and use 4 sand mills in series (fill fine oxidation Zirconium beads and coarse zirconia beads) are continuously sanded to make 15% fludioxonil · cartap SC;

Abstract

The invention relates to a rice seed treatment agent combining an insecticide with a fungicide and application of the rice seed treatment agent. The effective component of the combined insecticide is cartap hydrochloride; the effective component of the fungicide is fludioxonil; in the terms of the mass percentage, the content of the cartap hydrochloride is 50-1 percent and the content of the fludioxonil is 1-20 percent; the mixture ratio of the cartap hydrochloride to the fludioxonil is (30:1)-(1:40), preferably the mixture ratio is (20:1)-(1:20); and the cartap hydrochloride and the fludioxonil are added into a conventional additive and the mixture can be processed to form an agriculturally-general form. The insecticide and fungicide combined agent disclosed by the invention can be used for effectively controlling other seed-borne diseases such as bakanae disease of rice and aphelenchoides besseyi by adopting a seed coating method, a seed-immersion method and a shoot treatment method.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and relates to a combination of fludioxonil and cartap to kill insects and fungicides and a method for preventing and controlling rice seed-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 other fungal diseases. Due to long-term use, ric...
