Abstract
The invention discloses a bacteria medicament mixture for preventing and controlling weed in a rice field, which is characterized in that: curvularia lunata strain B6 (Wakker) Boedijn with the collection number of CGMGGNO.2928 and cyhalofop-butyl are adopted as active ingredients and proper solvent, surfactant, thickener and stabilizer are adopted as auxiliary materials, and then the active ingredients and the auxiliary materials are subjected to mechanical grinding to prepare a suspension system, wherein the concentration of the active ingredient curvularia lunata strain B6 is (0.1-10)*10<8>spores/ml, and the mixture comprises the following components in percentage by mass: 0.1 to 10 percent of cyhalofop-butyl, 1 to 10 percent of surfactant, 1 to 10 percent of stabilizer, 0.5 to 5 percent of thickener and the balance of solvent. The bacteria medicament mixture is used for preventing and controlling various kinds of weed in the rice field and has the advantages of safety for rice, wide weed controlling range and capability of controlling the weed in the entire growth period of the rice. The invention provides a new herbicide prepared by compounding stable and efficient post-emergence microorganisms with a chemical pesticide, and the new bacteria medicament mixture is environmental-friendly, prevents and controls various kinds of weed in the rice field and obviously increases the yield.
Description
Technical field
The present invention relates to a kind of novel microbial fungi and the composite herbicides for use in paddy of chemical pesticide, belong to field of agrochemicals.
Background technology
Curvularia lunata bacterium B6 (deposit number CGMGG No.2928; Depositary institution: China Committee for Culture Collection of Microorganisms common micro-organisms center; Depositary institution address: Datun Road, Chaoyang District, Beijing City; Preservation date, on March 5th, 2009; Classification name: curvularia lunata Curvularia lunata) be the weed killer herbicide fungi that recent studies on is developed; Show that through the lot of experiments result it has higher biologically active to paddy field barnyard grass grass, be used for paddy field prevent and kill off the barnyard grass grass have the preventive effect height, little to the eco-environmental impact in rice field, do not have residual toxicity, do not produce any poisoning, characteristics such as amount of increase in production is obvious.Its large usage quantity when yet this fungi is prevented and kill off paddy field weed, to kill the grass spectrum narrow, undesirable to the preventive effect of sedge family.Cyhalofop-butyl (cyhalofop-butyl), (R)-2-[4-(4-itrile group-2-fluorophenoxy) phenoxy group] butyl propionate, its chemical structural formula is following:
Belong to novel paddy field diphenyl ether selective herbicide, make cauline leaf and handle and to prevent and kill off paddy field barnyard grass grass and nutgrass flatsedge, have efficient, low toxicity, kill grass effect characteristics rapidly.
The main formulation of microbial bactericide use at present is aqua and wetting powder, and it is lower that aqua contains active component, and amount is bigger in packing, transportation, use, and use cost is higher; Though the wetting powder active component is higher,, have the dust drifting problem in packing, the use, and active component is influenced by carrier surface acidity or alkalescence and degrades in storage in processing.Oil-suspending agent is to be dispersed in the high dispersive that forms in the oil-phase medium, stable suspension system by active ingredient.Oil-suspending agent and aqua and wetting powder compare, and the former has stronger permeability and adhesiveness to the target crop, thereby has synergistic effect, because the former uses inert mineral oil and vegetable oil, active component is stable in storage.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art and defective; A kind of rice field microbial fungi and chemical pesticide compound herbicide are provided; Utilize the chemical pesticide cyhalofop-butyl to improve the activity of weeding of curvularia lunata bacterium B6, careless extremely spectrum; Give full play to its weeding characteristic; Make it can prevent and kill off all kinds of grassy weeds in rice field, sedge family, part broad leaved weed, thereby save human and material resources, minimizing because of using chemical pesticides in a large number to the pollution of environment and the harm of human body, the purpose that reach raising the output, increases income.
The present invention realizes that through following technical scheme weed killer herbicide of the present invention is an active ingredient with curvularia lunata bacterium B6 and cyhalofop-butyl, and is aided with the oil-suspending agent that solvent, surfactant and other auxiliary agent are prepared into, and each component is formed as follows:
Curvularia lunata bacterium B6 (0.1-10) * 10
8Individual spore/ml cyhalofop-butyl 0.1-10%

Said effective ingredient microorganism fungi is curvularia lunata bacterium B6, and its deposit number is CGMGG No.2928, (depositary institution: China Committee for Culture Collection of Microorganisms common micro-organisms center; Depositary institution address: Datun Road, Chaoyang District, Beijing City; Preservation date, on March 5th, 2009; The classification name: curvularia lunata Curvularia lunata) its concentration is (0.1-10) * 10
8Individual spore/ml, optium concentration is (0.5-5) * 10
8Individual spore/ml;
The chemical name of said active ingredient cyhalofop-butyl is: (R)-2-[4-(4-itrile group-2-fluorophenoxy) phenoxy group] butyl propionate, its mass percent example is 0.1-10, the best in quality percentage is 0.5-5; The chemical structural formula of cyhalofop-butyl is following:
Described solvent comprises vegetable oil and mineral oil, is one or more mixtures in peanut oil, soybean oil, palm oil, rapeseed oil, rice bran oil, sunflower oil, sesame oil, castor oil, tung oil, diesel oil, machine oil, the kerosene.
Said surfactant comprises one or more mixtures in anion, cation, the nonionic surfactant.Described thickener comprises one or more mixtures in kaolin, bentonite, atlapulgite, sepiolite, white carbon black, diatomite, precipitated calcium carbonate, talcum powder, plaster of paris chalky soil, potter's clay, imvite, the clay.
Said stabilizing agent comprises one or more mixtures in sucrose, urea, alginic acid, ethylene glycol, propane diols, the glycerine.
The present invention has following characteristics:
1. all kinds of weeds of paddy field there is preventive effect preferably.
To people and animals' low toxicity, to pest natural enemy safety, free from environmental pollution.
3. no dust drift in production and processing, use does not have caking, nonhygroscopic phenomenon in transportation, the storage.
4. strong, the anti-evaporating of permeability and adhesiveness, resistance of rainwater washing against, lasting period length, storage tolerance, obvious to crop safety, raising the output.
Prove with field trial through indoor; The present invention is used for paddy field and prevents and kill off all kinds of grass family, sedge family and broad leaved weed such as barnyard grass grass, eleusine indica, nutgrass flatsedge, difformed galingale herb etc.; To rice safety, broad weed-killing spectrum, a drug can be controlled paddy rice whole growth phase weeds, and administrated method is that weeds are wholeheartedly converted 200-2000 times of even spraying of water dilution during leaf phase to four leaf; The invention provides foliar herbicide novel form kind behind a kind of good bud, environmentally friendly, raising the output obviously.
