Benefits of technology

This patented solution helps protect against damage caused from pests such as rice borer (rice bulb worm) or root rot disease that can affect important agricultural products like wheat grain production. It works well with other plant protection methods but does little work for reducing harmful insects called rice hopper mite(Ramsey), also known as white grubsy weevils). By applying this technology multiple treatments at once, there will be an improved method for combating these destructive organisms without causing negative side-effects.

Problems solved by technology

This patented technical problem addressed in this patents relates to developing an efficient antifungal composition that combines various functions together without compromising their respective benefits over others when applied alone due to its low solubility in water compared to most commonly available agents like benzonapircetoclavine hydroxyimidocyanolate (BZ).

Embodiment 1

[0044] Weigh 20% cyproconazole, 40% tricyclazole, 3% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, U.S.), 2% diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde condensate), 3% pull open powder BX (sodium dibutyl naphthalene sulfonate), 2% K-12 (sodium lauryl sulfate), 3% diatomaceous earth, 5% glucose, and kaolin are added to 100% by weight. The above-mentioned raw materials are prepared through the conventional method for preparing water-dispersible granules, namely mixing, ultrafine airflow pulverization, mixing, and granulating steps to prepare 60% cyproconazole·tricyclazole water-dispersible granules. The formula is used to prevent and control rice blast. It is diluted and sprayed with water 3500 times, and the control effect is 95.4% 15 days after application. 10% Cyproconazole Suspension Concentrate 1000 times and 75% Tricyclazole WP 2000 times, using the same method, the control effect of 14 days after the drug is 73.2% and 85.6% respectively.

Embodiment 2

[0046] Weigh 10% cyproconazole, 50% tricyclazole, 3% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, U.S.), 3% diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde condensate), 2% pull open powder BX (sodium dibutyl naphthalene sulfonate), 1% K-12 (sodium lauryl sulfate), 1% carboxymethyl cellulose, 3% urea, diatomaceous earth added to 100% by weight share. The above-mentioned raw materials are prepared through the conventional method for preparing water-dispersible granules, namely mixing, ultrafine airflow pulverization, mixing, and granulating steps to prepare 60% cyproconazole·tricyclazole water-dispersible granules. The formula is used to prevent and control rice blast. It is diluted and sprayed with water 3000 times, and the control effect is 96.1% 14 days after application. 10% Cyproconazole Suspension Concentrate 1000 times and 75% Tricyclazole WP 2000 times, using the same method, the control effect of 14 days after the drug is 68.5% and 84.8% respect...

Embodiment 3

[0048] Weigh 5% cyproconazole, 75% tricyclazole, 4% TERSPERSE 2700 (polycarboxylate, produced by Huntsman, U.S.), 2% diffusing agent NNO (alkyl naphthalene sulfonate formaldehyde condensate), 2% pull open powder BX (sodium dibutylnaphthalene sulfonate), 2% K-12 (sodium lauryl sulfate), 3% corn starch, 5% ammonium sulfate, and attapulgite are added to 100% by weight. 80% cyproconazole · tricyclazole water dispersible granules are prepared by the conventional method of preparing water dispersible granules from the above raw materials, ie mixing, ultra-fine airflow pulverization, mixing and granulation. The formula is used to prevent and control rice blast. It is diluted and sprayed with water 3000 times, and the control effect is 93.6% within 14 days after application. 10% Cyproconazole Suspension Concentrate 1000 times and 75% Tricyclazole WP 2000 times, using the same method, the control effect of 14 days after the drug is 72.8% and 84.2% respectively.

Abstract

The invention discloses a bactericidal composition containing cyproconazole. The weight ratio of the cyproconazole to isoprothiolane is 5:1-1:20. The composition can be prepared into a water dispersible granule, wettable powder, a suspending agent, a dispersible oil suspending agent, microemulsion or an emulsifiable concentrate. The bactericidal composition has the beneficial effects that the bactericidal composition is used for preventing and treating pyricularia oryzae, rhizoctonia solani and ustilaginoidea virens, is reasonable in components, has prevention and treatment effects and is good in sterilizing effect and wide in prevention and treatment spectrum; the three diseases including pyricularia oryzae, rhizoctonia solani and ustilaginoidea virens are prevented and treated through one-time pesticide application, so that the pesticide use frequency is reduced, the pesticide use cost is low, and the activity and the sterilizing effect of the bactericidal composition on the pyricularia oryzae are not simply superposed by the activity of all the components, but have remarkable synergistic effect; and the generation of the resistance is retarded, the crop safety is good, and the bactericidal composition conforms to the safety requirements of pesticide preparations.
