Abstract

One new technology of pre- preventing peach brown rot, belongs to fruit tree disease prevention and cure field, to solve the deficiency in current peach brown rot Prevention Technique, invents a technology for pre- preventing peach brown rot.Take the time of the year when autumn changes into winter to combine prune, strengthen the modes such as orchard management, the ventilation and penetrating light in attention peach garden and draining, humidity in reduction garden, increasing application phosphorus potassium fertilizer, medicament protection, can effectively prevent and treat the generation of brown rot, reduce management difficulty, improve peach yield.

Description

One preventionPeach brown rotNew technology

Technical field

The present invention relates to fruit tree disease prevention and cure field, a specifically Prevention Technique for peach brown rot.

Background technology

Peach brown rot also known as sclerotiniose, are one of Major Diseases of peach.The fruit of main harm peach, also endangers flower, leaf and the young spray tip.Rainy moist time permanent current row causes disaster, and causes a large amount of decayed fruits.Germ also endangers the tone fruit trees such as Lee, apricot, cherry in addition to peach is endangered.Especially fructescence meets the rainy weather of a run of wet weather, will cause the big generation of the disease, and considerable damage is caused to orchard.

The content of the invention

The present invention invents a technology for pre- preventing peach brown rot to solve the deficiency in current peach brown rot Prevention Technique.

The present invention is in order to solve the above technical problems, adopted the technical scheme that, a new technology for preventing and treating peach brown rot, its special character includes following process engineering：

1st, time of the year when autumn changes into winter combination is pruned, and thoroughly removes sick branch, withered branch, mummy and the ground shedding set in garden, is concentrated and is burnt or buried, reduces primary source of infection.When bud is existing red, 5 Baume degrees lime sulfurs of spray are sterilized.Strengthen orchard management, note ventilation and penetrating light and the draining in peach garden, humidity in reduction garden, increasing application phosphorus potassium fertilizer etc., strengthen tree vigo(u)r, improve tree body resistance against diseases, mitigate disease.Tried one's best when the harvesting of peach fruit, storing and avoid causing wound, reduce pathogen infecting during storing and transporting；It was found that disease fruit, picks treatment in time；2nd, the fruit easily susceptible time is late April to May.Medicament protection is to prevent and treat the sick key measure.To 3 weeks before fruit picking after fallen flowers, 1 medicine was sprayed every 10 ~ 15 days.Conventional medicament has：70% 600 ~ 800 times of thiophanate methyl wettable powder liquid, 65% 500 times of Zineb wettable powder liquid, 4% 1500 times of pyrimidine nucleoside liquid, 2000 times of liquid of kresoxim-methyl etc. have good prevention effect to peach brown rot；3rd, repeat spray, into June can also emphasis spray zinc sulfate Bordeaux mixture（Zinc sulfate: lime: water is 1: 2: 240）2 ~ 3 times, 10 ~ 15 days 1 time.Also there is good prevention effect, and will not develop immunity to drugs.

Technique effect

The solution have the advantages that, using above-mentioned technical scheme, it is possible to achieve a new technology for peach brown rot, the method is simple to operate, the generation of brown rot can be effectively prevented and treated, management difficulty is reduced, improve peach yield.

Specific embodiment

1st, time of the year when autumn changes into winter combination is pruned, and thoroughly removes sick branch, withered branch, mummy and the ground shedding set in garden, is concentrated and is burnt or buried, reduces primary source of infection.When bud is existing red, 5 Baume degrees lime sulfurs of spray are sterilized.Strengthen orchard management, note ventilation and penetrating light and the draining in peach garden, humidity in reduction garden, increasing application phosphorus potassium fertilizer etc., strengthen tree vigo(u)r, improve tree body resistance against diseases, mitigate disease.Tried one's best when the harvesting of peach fruit, storing and avoid causing wound, reduce pathogen infecting during storing and transporting；It was found that disease fruit, picks treatment in time；2nd, the fruit easily susceptible time is late April to May.Medicament protection is to prevent and treat the sick key measure.To 3 weeks before fruit picking after fallen flowers, 1 medicine was sprayed every 10 ~ 15 days.Conventional medicament has：70% 600 ~ 800 times of thiophanate methyl wettable powder liquid, 65% 500 times of Zineb wettable powder liquid, 4% 1500 times of pyrimidine nucleoside liquid, 2000 times of liquid of kresoxim-methyl etc. have good prevention effect to peach brown rot；3rd, repeat spray, into June can also emphasis spray zinc sulfate Bordeaux mixture（Zinc sulfate: lime: water is 1: 2: 240）2 ~ 3 times, 10 ~ 15 days 1 time.Also there is good prevention effect, and will not develop immunity to drugs.

Claims (1)

1. the new technology of preventing and treating peach brown rot, it is characterized in that：When bud is existing red, 5 Baume degrees lime sulfurs of spray are sterilized；To 3 weeks before fruit picking after fallen flowers, 1 medicine was sprayed every 10 ~ 15 days；Conventional medicament has：70% 600 ~ 800 times of thiophanate methyl wettable powder liquid, 65% 500 times of Zineb wettable powder liquid, 4% 1500 times of pyrimidine nucleoside liquid, 2000 times of liquid of kresoxim-methyl etc. have good prevention effect to peach brown rot；Zinc sulfate Bordeaux mixture is sprayed into June emphasis 2 ~ 3 times, 10 ~ 15 days 1 time.
