Abstract
The invention discloses a pyraclostrobin-containing pesticide composition for preventing and treating rice bakanae disease, and an application for the same, which belong to the technical field of preventing and treatment for rice bakanae disease. The pesticide composition contains pyraclostrobin and cartap, wherein the mass ratio of the effective ingredients of pyraclostrobin and cartap is (1-40): (1-20). According to the pesticide composition and the application disclosed by the invention, pyraclostrobin is used as a main effective ingredient for preparing a rice seed-soaking medicament in a compounding manner, and the medicine-resistant harm of rice bakanae disease on carbendazim and prochloraz can be effectively overcome. Moreover, pyraclostrobin is a bionic compound, and good in compatibility on environment and safety on crops in case of being applied to rice seed-soaking.
Description
Technical field
The present invention relates to a kind of composition pesticide and uses thereof, especially a kind of composition pesticide and application thereof take pyraclostrobin and cartap as main active.This composition pesticide is mainly used in the seed soaking of rice paddy seed, belongs to bakanae disease of rice Prevention Technique field.
Background technology
Bakanae disease of rice is the fungal disease that a kind of systematicness of hazard rice overground part infects, and is distributed widely in each rice district, the world, mainly is distributed in the torrid zone and paddy rice producing region, temperate zone.At Asia, the loss of bakanae disease reaches as high as 70%.China occurs more with areas such as Guangdong, Guangxi, Hunan, Jiangxi, Shanghai, Zhejiang, Jiangsu, Anhui and Liaoning, and occurs seriously to have become a major issue of Rice Production.The morbidity field general underproduction 10% one 20%, but the serious underproduction of morbidity is more than 50%.In recent years, along with the popularization of the continuous expansion of japonica rice area, non-irrigated seedling-cultivation technique and the application and development of seedling cultivation of rice transplanting technology, bakanae disease of rice is and spreads development trend.
Bakanae disease of rice is that a kind passes system's disease, and the infective pathogen bacterium is imperfect fungus fusarium moniliforme (Fusarium moniliform sheld).Mainly to put prevention first, without treatment means, unique prophylactico-therapeutic measures is that the pathogen that survives the winter in the seed is killed in the medicament seed soaking to this sick control strategy after the morbidity.The eighties in 20th century, the benzimidazole medicament take carbendazim as representative is registered prevents and treats bakanae disease of rice, and after such medicament and the built agent that is followed successively by main component were applied, the bakanae disease of rice state of an illness had obtained effective control.But because the single easy sudden change in pharmacy effect site, long-time use along with similar medicament, the encode codon GAG(glutamic acid of 198 amino acids of medicament Main Function site b-tub microtubule protein gene) sport the GCG(alanine), cause fusarium moniliforme that the resistance of such benzimidazole medicament is obviously risen, to middle nineteen nineties, the benzimidazole medicament exhausts in the high area of resistance level substantially to the preventive effect of bakanae disease of rice.At the beginning of the nineties, the imidazoles bactericide take Prochloraz as representative is a dark horse, and replaces rapidly the carbendazim that preventive effect obviously descends, and becomes the first-selected medicament that China prevents and treats bakanae disease of rice.But along with the long-term single use of Prochloraz, the risk that Prochloraz is prevented and treated bakanae disease is also very obvious.Therefore, the screening pharmaceutical preparations of preventing and treating safely and efficiently bakanae disease of rice has become a urgent task in the current Rice Production.
Pyraclostrobin is a kind of methoxy acrylic bactericide, has protection, treatment and eradicant action, thereby hinders the synthetic bactericidal effect that reaches of energy by the respiration that suppresses pathogen.Pyraclostrobin is a kind of imitation biochemistry compound, has good Environmental compatibility and to the safety of crop.This medicament is mainly used in preventing and treating the economic crops diseases such as fruit tree, vegetables.
Summary of the invention
The objective of the invention is provides a kind of new bakanae disease of rice composition pesticide of preventing and treating for the resistance problem that bakanae disease of rice forms relevant bactericide, reduces because the loss that causes rice yield of bakanae disease.
Purpose of the present invention realizes by following measures:
A kind of pyraclostrobin-containing is prevented and treated the composition pesticide of bakanae disease of rice, it is characterized in that containing pyraclostrobin and cartap, and wherein the active ingredient mass ratio of pyraclostrobin and cartap is: 1-40:1-2.
Described composition pesticide, wherein pyraclostrobin and cartap and known auxiliary agent and excipient are re-dubbed any one formulation that allows on the agricultural chemicals.
Described dispersant: NNO, lignosulfonates, naphthalene sulfonate, polymeric carboxylic salt.
Described emulsifier: phenethyl phenol polyethenoxy ether phosphate, polyoxyethylene nonylphenol ether, Nongru-700 #, farming breast 2201 etc.
Described wetting agent: the compounds such as alkylphenol-polyethenoxy base ether formaldehyde condensation products sulphate, alkylphenol-polyethenoxy base ether phosphate, alkylsulfonate, alkyl sulfate, methoxyl group fatty acid amido benzene sulfonate.
Described filler: bentonite, kaolin, aluminium-magnesium silicate, water.
Described solvent: dimethylbenzene, solvent naphtha, toluene etc.
Above-mentioned pyraclostrobin-containing is prevented and treated the composition pesticide of bakanae disease of rice and is used, and is used for preventing and treating bakanae disease of rice.
The present invention uses pyraclostrobin as the main composite manufacturing rice seed soaking of active ingredient medicament, can effectively overcome fusarium moniliforme to the pesticide resistance harm of carbendazim and Prochloraz.And the pyrazoles Fluoxastrobin is a kind of imitation biochemistry compound, is applied to that rice seed soaking has good compatibility to environment and to the safety of crop.
Embodiment:
Embodiment 1
Pyraclostrobin 1 gram, cartap 2 are restrained, methoxyl group fatty acid amido benzene sulfonic acid sodium salt 0.2 is restrained, dispersing agent NNO 0.4 gram, kaolin adds to 10 grams, fully mixes and at a high speed pulverizing, makes wetting powder.
Embodiment 2
With pyraclostrobin 4 grams, cartap 0.1 gram, phenethyl phenol polyethenoxy ether phosphoesterase 30 .3 gram, polyoxyethylene nonylphenol ether 0.2 gram, propane diols 0.5 gram, 10 milliliters of deionized waters utilize high-shear homogenizer to stir, the aqueous emulsion of system.
Application example
The composition pesticide seed soaking that makes with above-mentioned example prevents and treats the bakanae disease of rice test.
Test is processed: this medicament of testing each embodiment manufacturing all adopts 2000 times of aqueous solution seed soaking, with 25% Prochloraz missible oil medicament in contrast.Be respectively town rice No. 16 and 7979-1 for the rice varieties that tries the water.25 ℃ of soaking temperatures, seed soaking time 48 hours, vernalization is to the sowing that shows money or valuables one carries unintentionally behind the seed soaking enough time.Seedling raising method is non-irrigated seedling, transplants the land for growing field crops after 20 days length of time rice seedlings grow.Tillering stage and Filling stage investigation bakanae disease strain rate are also calculated preventive effect.
Result of the test shows, after adopting the embodiment of the invention 1, embodiment 2 seed soaking, paddy rice seed-borne disease bakanae disease is had good preventive effect, the kind town rice 16 higher to bacterial bearing rate, the effect of controlling bakanae disease in its tillering stage and booting stage is higher than 2500 times of contrast medicament-25% Prochloraz missible oil far away.The test control efficiency of rice varieties 7979-1 is all more than 90%, and preventive effect is higher than the contrast medicament equally.The results are shown in Table 1, table 2.
Table 1, the embodiment of the invention are made medicament to the control efficiency kind of bakanae disease of rice: town rice 16
The medicament of table 2, embodiment of the invention manufacturing is to the preventive effect kind of bakanae disease of rice: 7979-1
