Abstract
One plant growth protectant, the composite bactericide pesticide for the treatment of wheat disease is used to prevent and treat the main disease head blight of wheat class, powdery mildew, rust etc.With methyl-benzimidazole-2-carbamates (carbendazim) and the composite sterilization host of making of 1-(4-chlorophenoxy)-3,3 dimethyl-1-(1-hydrogen-1,2,4-triazoles-1-yl) butanone (triadimefon).Be aided with auxiliary agent carboxymethyl cellulose and/or sodium alkyl benzene sulfonate and potter's clay and make the spraying agent, or add water with auxiliary pva and make kind of a clothing agent.Pesticide for the treatment of wheat disease has complementary synergy, and a dispenser reduces the labour, saves the advantage of cost.
Description
The invention relates to a plant growth protectant, particularly a kind of composite bactericide is applicable to control wheat class multiple diseases, and is especially essential for the regional integrated control gibberella zeaze petch of wheat and barley in China middle and lower reach of Yangtze River, powdery mildew, rust three big diseases.
Pesticide for the treatment of wheat disease of the present invention is on the basis of research main disease decreasing and increasing law of China middle and lower reach of Yangtze River Mai Qu and control strategy, according to the integrated control general design requirement, succeeds in developing by a large amount of composite reagents, screening.Before the present invention made, common way was the different emergence periods according to different diseases, imposes various special effect agents respectively pointedly.This method spraying times is many, the drug cost height.For attempting to reach the purpose more a medicine is prevented, controlled, the applicant had once released the carbendazim jinggangmycin, composite dose of carbendazim sulphur, carbendazim tmtd etc., but add up owing to these effects of composite dose show as effect at the most, that have even the drug effect antagonism occurs, so effect is all undesirable.
Task of the present invention provides the composite bactericide of the complementary synergy of a kind of effect, and this composite bactericide can satisfy a dispenser and can reach the purpose of preventing and treating each main wheat disease of China middle and lower reach of Yangtze River Mai Qu.
The scheme of finishing task of the present invention is, the sterilization host of pesticide for the treatment of wheat disease is selected methyl-benzimidazole-2-carbamates (carbendazim) and 1-(4-chlorophenoxy)-3,3 dimethyl-1-(1-hydrogen-1,2,4 triazol-1-yls) composite the forming of butanone (triadimefon), the composite weight ratio of sterilization host effective ingredient is: triadimefon: carbendazim=1: 4～50, its valid density are 5～51 weight %.According to different insecticide-applying way, can be aided with different auxiliary agents and make and spray agent, plant the clothing agent.The composite weight ratio of sterilization host effective ingredient that sprays agent is a triadimefon: carbendazim=1: 10～50, valid density is 11～51 weight %, the composite weight ratio of sterilization host active ingredient of planting the clothing agent is a triadimefon: carbendazim=1: 4～10, valid density are 5～11 weight %.But pesticide for the treatment of wheat disease sprays agent used additives carboxymethyl cellulose and/or sodium alkyl benzene sulfonate and adds that potter's clay is composite to form, and its additive dosage is 2～10 weight %.The available auxiliary pva of pesticide for the treatment of wheat disease kind clothing agent adds that water is composite to form, and its additive dosage is 3～7 weight %.
So the composite bactericide pesticide for the treatment of wheat disease that constitutes adopts composite the making of conventional pesticide preparation method.
Pesticide for the treatment of wheat disease of the present invention has following advantage:
1, the sick effect of the main wheat of integrated control is better than existing various medicament, through field multiple spot probationary certificate, is 82.4～83.4% to the preventive effect of head blight, is 84.2～91.5% to the effect of powdery mildew, and the effect of bar rust and leaf rust is 90%.Can reach with kind of a clothing agent control wheat sharp eyespot does not have withered dead ears substantially, is better than all kinds of seed treatments.It is 16.8～54.5% that disease is sent out year effect of increasing production of use pesticide for the treatment of wheat disease greatly, average out to 38.1%.
2, pesticide for the treatment of wheat disease has been brought into play composite dose of multidigit point, multipath bactericidal mechanism, and complementary synergy is fairly obvious, measures minimum inhibitory concentration to the head blight mycelia with the diaphragm method, and pesticide for the treatment of wheat disease, carbendazim, triadimefon are followed successively by 1,2,200PPM.Measure the sporulation inhibition concentration with succusion, pesticide for the treatment of wheat disease is respectively than low 5 times and 100 times of carbendazim, triadimefon.Concentration during mensuration suppresses the powdery mildew spore germination, pesticide for the treatment of wheat disease, carbendazim, triadimefon are respectively 4,120,9.5PPM.Pesticide for the treatment of wheat disease is respectively 480.0 and 2181 to the co-toxicity coefficient of gibberellic hypha and white powder germ.
3, use each main disease of pesticide for the treatment of wheat disease control wheat class to have a medicine and control more, reduce the labour, save the effect of cost.
4, enlarge antimicrobial spectrum, delay the generation of germ resistance.
Embodiment 1:
Pesticide for the treatment of wheat disease sprays agent, host is carbendazim and triadimefon, the weight ratio of triadimefon and carbendazim is 2: 45, the valid density of host is 47 weight %, auxiliary agent is carboxymethyl cellulose 5 weight % and sodium alkyl benzene sulfonate 5 weight %, add potter's clay to 100 weight %, make pesticide for the treatment of wheat disease of the present invention and spray agent so that conventional method is composite.
Embodiment 2
The agent of pesticide for the treatment of wheat disease kind clothing, host is carbendazim and triadimefon, and the weight ratio of triadimefon and carbendazim is 1: 5, and the valid density of host is 6 weight %, and auxiliary agent is polyvinyl alcohol 5 weight %, adds water to 100 weight %, makes the agent of pesticide for the treatment of wheat disease kind clothing so that conventional method is composite.
