Abstract
A kind of method that the invention provides medical treatment late blight of potato, it is characterized in that (1) when Rhizoma Solani tuber osi early squaring is not fallen ill, in mass ratio 75% Mancozeb of every mu of Herb spraying for the first time: water is the mixed preparing liquid 40～50 of 1:450～600；(2), when field finds " primary infection focus ", every mu of Herb spraying is the most auspicious all for the second time: Sandofan: water is the mixed preparing liquid 40～50 of 1:3～4:1500～1800；(3) after second time spray medicine 7～10 days, every mu of Herb was sprayed the mixed preparing liquid 40～50 that Yin Fali in mass ratio: water is 1:600～700 for the third time.Present invention prevention and treatment are laid equal stress on, and make the late blight of potato occur with popular and have obtained effective control, and the medicament categories that the present invention each stage uses is different, reduces Drug resistance, improves the effect of the medical treatment late blight of potato.
Description
Technical field
A kind of method that the present invention relates to medical treatment late blight of potato.
Background technology
The late blight of potato by phytophthora infestans [phytophthora infestans(Mont.) deBary] Rhizoma Solani tuber osi that causes is a kind of universal and endanger serious disease during producing.Because late blight makes potato plant the most withered, cause the loss of yield and the reduction of quality, the serious time underproduction more than 50% occurs.Medical treatment is the important means of late blight of potato preventing and treating, but at present medical treatment late blight of potato method is to be auxiliary, treatment based on prevention, select to select same type or same medicament during different phase medicine, such one is that popular being difficult to of the late blight of potato is effectively controlled, two is that different phase uses same type or same medicament, Drug resistance strengthens, and drug effect lowers.As Chinese patent application CN101971768 A discloses a kind of method preventing and treating the late blight of potato, its method is late blight their early stage, per hectare 25% dilute trifloxystrobin EC600～750 milliliters are watered 600 kilograms, it is made into medicinal liquid, to Rhizoma Solani tuber osi Herb even spraying, general spray medicine 2～3 times, be spaced 7～8 days.And for example Chinese patent CN102577810
B discloses the prevention and controls of a kind of late blight of potato, and wherein chemical prevention link is for using systemic fungicide to treat at late blight early period of origination.
Summary of the invention
It is an object of the invention to for above-mentioned weak point, it is provided that a kind of method that prevention and treatment are laid equal stress on, reduced the drug-fast medical treatment late blight of potato, make that the late blight of potato is popular to be effectively controlled, and improve the effect of the medical treatment late blight of potato.
The present invention is achieved in that
1, when Rhizoma Solani tuber osi early squaring is not fallen ill, every mu of Herb spraying in mass ratio 75% Mancozeb for the first time: water is the mixed preparing liquid 40～50 of 1:450～600；
2, when field finds " primary infection focus ", every mu of Herb spraying is the most auspicious all for the second time: Sandofan: water is the mixed preparing liquid 40～50 of 1:3～4:1500～1800；
3, after second time spray medicine 7～10 days, every mu of Herb was sprayed the mixed preparing liquid 40～50 that Yin Fali in mass ratio: water is 1:600～700 for the third time.
In the present invention, when early squaring is not fallen ill, carry out Herb spraying first by Mancozeb, prevent and control the generation of the late blight of potato.Mancozeb is a kind of excellent protective fungicide, belongs to low-toxin farm chemicals, is not likely to produce resistance, and manganese, zinc microelement have the strong effect of significantly rush to crop, improve plant resistance against diseases.When field finds " primary infection focus ", use " auspicious all+Sandofan " mixed preparing liquid to carry out Herb spraying, can effectively treat the late blight of potato and control spreading of the late blight of potato.Auspicious all be 25% mandipropamid suspending agent; its mechanism of action mandipropamid is by disturbing phospholipid and the biosynthesis of cell wall deposit of pathomycete; reach to suppress spore germination and mycelial growth purpose; can be rapidly absorbed by blade; and rest in leaf table wax coat, blade is shielded.Sandofan has another name called Wakil MnZn, is a kind of high-efficiency low-toxicity systemic fungicide with protection, therapeutical effect, after being absorbed by plant roots, stem, leaf, can be transmitted to each organ, resistance of rainwater washing against in plant body, and the lasting period is long.Second time spray medicine after 7～10 days, third time uses Yin Fali to carry out Herb spraying, Yin Fali is the novel mixture compounded by curative fungicide agent fluopicolide and strong Uptake and translocation antibacterial propamocarb, fluopicolide mainly acts on cell membrane and intercellular specific proteins and shows bactericidal activity, unique thin layer penetrance can strengthen the lateral conductivity of medicament and longitudinally fed power, good inhibitory activity, treatment potential is all had to highlight each Main Morphology of pathogen；Propamocarb has stronger Uptake and translocation, can conduct the most up and down after soil treatment, also can be distributed in rapidly in blade after foliar spray, medication can play a role for 30 minutes, and all kinds of crop late blights causing Oomycete fungal show the prevention effect of super excellence.Yin Fali makes two kinds of effective ingredient potentiations notable.
It is that for the first time spray medicine uses that to put prevention first, treat be auxiliary measure that the present invention prevents and treats the method for the late blight of potato, second time spray medicine have employed prevention and treats the measure laid equal stress on, third time spray medicine uses treatment to be main measure, make the late blight of potato occur with popular and obtain effective control, and the medicament categories that each stage uses is different, reduce Drug resistance, improve the effect of the medical treatment late blight of potato.Using the present invention, the disease index of the late blight of potato can control in 14, and prevention effect can prevent and treat late blight of potato method mu volume increase fresh potato potato 27%～30% with 52.6%～55.45% than conventional medicine.
Detailed description of the invention
1, when Rhizoma Solani tuber osi early squaring is not fallen ill, after mu is watered 45kg mix homogeneously with 75% Mancozeb 75g～100g for the first time, Herb is sprayed；
2, when field finds " primary infection focus ", after mu is watered 45kg mix homogeneously with auspicious all 25 ml～30ml+ Sandofan 75g～100g for the second time, Herb is sprayed；
3, second time spray medicine after 7～10 days, after mu Yin Fali 60ml～75ml is watered 45kg mix homogeneously for the third time Herb spraying.
Above spraying time is at fine day, to improve prevention effect.
