Abstract
一种用于水稻田杂草防除的菌药合剂，其特征是以新月弯孢霉菌B6(Curvularia lunata(Wakker)Boedijn，保藏编号为CGMGG No.2928)、氰氟草酯为有效成分，并辅之以适当的溶剂、表面活性剂、增稠剂、稳定剂，经机械研磨制备成的悬浮体系，其中有效成分新月弯孢霉菌B6的浓度为(0.1-10)×108个孢子/ml，氰氟草酯的质量百分比例为0.1-10，表面活性剂质量百分比为1-10，稳定剂质量百分比为1-10，增稠剂质量百分比为0.5-5，溶剂补齐至100％；本发明用于水稻田中防除各类杂草，对水稻安全、杀草谱广，一次用药可以控制水稻整个生长期的杂草；本发明提供了一种稳定、高效芽后微生物与化学农药复配除草剂新剂型品种，该新型菌药合剂对环境友好、防除水稻田各类杂草而且增产明显。A bacterium-drug mixture for controlling weeds in paddy fields, characterized by using Curvularia lunata (Wakker) Boedijn (Curvularia lunata (Wakker) Boedijn, preservation number CGMGG No.2928) and cyhalofop-ester as active ingredients, and Supplemented with appropriate solvents, surfactants, thickeners, and stabilizers, the suspension system is prepared by mechanical grinding, in which the concentration of the active ingredient Curvularia lunata B6 is (0.1-10)×10 8 spores/ ml, the mass percent of cyhalofop-ethyl is 0.1-10, the mass percent of surfactant is 1-10, the mass percent of stabilizer is 1-10, the mass percent of thickener is 0.5-5, and the solvent is replenished to 100% The present invention is used for controlling various weeds in paddy fields, is safe to paddy and has a wide herbicidal spectrum, and can control the weeds in the whole growth period of paddy with one application; Formulated with a new herbicide dosage form, the new fungus-drug mixture is environmentally friendly, can control various weeds in paddy fields, and can significantly increase production.
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%
Surfactant 0.1-10% stabilizing agent 1-10%
Thickener 0.5-5% solvent polishing to 100%
