Abstract
The invention relates to a compound pesticide for protecting and curing rice sheath blight, which belongs to the technical field of compound pesticides. The compound pesticide is characterized by containing 0.15-25 percent of thifluzamide and 1-50 percent of validamycin. The compound pesticide for protecting and curing the rice sheath blight is prepared by compounding the thifluzamide and the validamycin and has good protecting and curing effect; and field trials shows that the protecting and curing rate of the compound pesticide can reach 98 percent. The compound pesticide has strong persistence and prolongs the period of validity of protecting and curing the rice sheath blight to be 30 days; and the production cost of the compound pesticide is lower and is reduced by more than 50 percentcompared with a pesticide which singly uses the thifluzamide.
Description
Technical field
The invention belongs to technical field of compounded pesticide, be specifically related to a kind of Recompounded pesticide of preventing and treating rice sheath blight disease.
Background technology
Rice sheath blight disease is a kind of common disease, the frequently-occurring disease of China paddy rice.Common have a jinggangmeisu etc., and jinggangmeisu claims valida again, belongs to the low toxicity bactericide.The big mouse acute oral of pure product LD50 is all greater than 2000 milligrams/kilogram, and hypodermic injection LD50 is all greater than 1500 milligrams/kilogram.Smear rat skin for 5000 milligrams/kilogram and do not have toxic reaction.To the fish low toxicity, carp TLM (96h) LD50＞40 mg/litre.Formulation has 5%, 10% aqua and 5%, 20%, 28% water solube powder.It is a kind of antibiotic of actinomycetes generation, has stronger interior absorption, is easily absorbed by somatic cells and conduction rapidly within it, disturbs and inhibition somatic cells g and D.Be mainly used in rice sheath blight disease, also can be used for the control of crop pests such as rice green smut and vegetables and cotton, shortcoming is that the lasting period is short generally at 10-15 days.
Thifluzamide claims thiophene fluorine bacterium amine (thifluzamide) again, is the efficient systemic fungicide of thiazole carboxyl N-benzamides.Be suitable on paddy rice using multiple diseases such as preventing and treating banded sclerotial blight, belong to thifluzamide and belong to the low toxicity bactericide, the oral and rabbit of 24% thifluzamide suspending agent rat acute acute through skin LD50 greater than 5000 mg/kg.No teratogenesis, mutagenesis, carcinogenesis.It is applicable to multiple application methods such as foliar spray, seed treatment and soil treatment, is the outstanding bactericide of various crop diseases such as control paddy rice, peanut, cotton, beet, potato and lawn.Be mainly used in paddy rice, prevent and treat rice sheath blight disease.2.24% thifluzamide suspending agent is a thiazole carboxyl N-benzamides bactericide, has very strong interior suction conductivity, can prevent and treat plurality of plant diseases, particularly the caused disease of basidiomycetes Rhizoctonia fungi.Its shortcoming is to cost an arm and a leg, the use cost height.
