Abstract
The invention discloses a mixed pesticide for preventing and controlling melasma and cercospora brown spot of peanut. The pesticide is prepared from the following raw materials in parts by weight: 6-18 parts of propineb, 1-3 parts of tebuconazole and 500-12600 parts of water. The dosage of propineb is 30g/mou, and the dosage of tebuconazole is 5g/mou. The propineb and the tebuconazole are matched in the weight ratio of 6:1 per mou, and then 500-600 times of solution is added. The pesticide is applied twice in the primary disease incident period, and the interval of the pesticide application is 10-14 days. The invention can effectively control the peanut melasma, but also can obviously inhibit the cercospora brown spot of peanut, thereby achieving the purpose of one pesticide with multiple functions. The invention reduces the pesticide applying amount, prolongs the effect time, reduces the pesticide applying times, lightens the environment pollution, and is favorable for the ecological balance.
Description
Technical field
The present invention relates to technical field of pesticide, particularly control Mixed Pharmacy and the using method thereof of a kind of cercospora leaf spot of groundnut and brown spot.
Background technology
The cercospora leaf spot of groundnut claims again late pinta, is commonly called as " black subcutaneous ulcer ", " black puckery " sick etc., is peanut producing region both at home and abroad modal leaf section fungal disease.Onset peak comes across the middle and late growth stage of peanut more, therefore the title of " late spot " disease is arranged.Often cause plant to fall leaves in a large number, cause the pod impaired development, output falls sharply.Cercospora leaf spot of groundnut scab is pitchy, usually there is no yellow haloing on every side, or narrower, unconspicuous faint yellow haloing is arranged.On the leaf back scab, usually produce many black points (germ stroma), become the concentric wheel stripe shape, and one deck pitchy mustiness thing, i.e. germ conidiophore and conidium are arranged.When disease is serious, produce a large amount of scabs, cause that blade is withered to come off.Infection process stem stalk produces the pitchy scab, and depression makes the blackening of stem stalk withered when serious.
The cercospora brown spot of peanut is one of the most serious leaf diseases in Peanut producing region, claims again early pinta of peanut.Each peanut of China producing region generally occurs, be distribute on China's peanut the widest, one of the heaviest disease causes harm.The general underproduction 10%-20% of the field of being injured, the serious underproduction is more than 40%.Cercospora brown spot of peanut main harm blade, when serious, petiole, cane also can be injured.Brown spot produces yellowish-brown or ferrugineous syringe needle shape fleck at the initial stage of a disease on peanut leaf, along with the disease development, constantly expand as circular or irregular shape scab, scab diameter 4-10mm, the positive yellowish-brown of scab is to dark brown, back side yellowish-brown, yellow haloing on every side is wide and obvious.Sometimes connect together when scab is many, form larger, irregular scab.Scab on cane, petiole or stipule be brown to pitchy, oblong.
At present, the medicament of preventing and treating the cercospora leaf spot of groundnut, the normal use of brown spot is Propineb or the Tebuconazole of single use, although it has played the effect of certain diseases prevention control disease, has many shortcomings.For example, I. has produced certain resistance due to single use.II. dosage is larger, and drug waste, environmental pollution phenomenon are heavier.
In view of the foregoing, a kind ofly can effectively prevent and treat the cercospora leaf spot of groundnut in the urgent need to occurring, can obviously suppress the cercospora brown spot of peanut again, the purpose of performance one medicine multiple-effect.And the minimizing pesticide dosage extends effective drug duration, reduces spraying times, alleviates environmental pollution, is beneficial to the Mixed Pharmacy of the ecological balance.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of and can effectively prevent and treat the cercospora leaf spot of groundnut, can obviously suppress the cercospora brown spot of peanut again, the purpose of performance one medicine multiple-effect.And the minimizing pesticide dosage extends effective drug duration, reduces spraying times, alleviates environmental pollution, is beneficial to Mixed Pharmacy and the using method thereof of the ecological balance.
In order to achieve the above object, the invention provides the control Mixed Pharmacy of a kind of cercospora leaf spot of groundnut and brown spot, wherein, comprise according to the following material of mass fraction than configuration:
6～18 parts of Propinebs
1～3 part of Tebuconazole
500～12600 parts, water.
Can also be the following material according to the configuration of mass fraction ratio:

Can also be the following material according to the configuration of mass fraction ratio:
6～12 parts of Propinebs
1～2 part of Tebuconazole
4200～7000 parts, water.
Goal of the invention to better implement the present invention, the present invention also provides the using method of the control Mixed Pharmacy of a kind of cercospora leaf spot of groundnut and brown spot, wherein, comprises the steps:
A, with two kinds of active ingredient Propinebs of described Mixed Pharmacy and Tebuconazole according to mass fraction than configuration, its allocation ratio is 6: 1;
B, on the basis of step a, add entry and fully dissolving, its mass fraction ratio with water is 1: 500～600, obtains Mixed Pharmacy.
Every mu of consumption of Propineb is 30 grams, and every mu of consumption of Tebuconazole is 5 grams.
At the their early stage of black spot and/or brown spot, described Mixed Pharmacy is sprayed dispenser 2 times.
Be 10～14 days the interval of spraying dispenser.
The present invention has following advantage:
1, provide a kind of new cercospora leaf spot of groundnut and the control medicament of brown spot, its effect can effectively prevent and treat the cercospora leaf spot of groundnut, can obviously suppress the cercospora brown spot of peanut again, the purpose of performance one medicine multiple-effect.
2, configuration technique is simple, and only need spray at the initial stage of a disease 2 times during dispenser, has reduced pesticide dosage, alleviates environmental pollution, is beneficial to the ecological balance.
3, other new agricultural chemicals proportioning, more be conducive to the elimination of black spot and/or the brown spot of resistance.
