Abstract

The invention provides a hawthorn physalospora piricola preventing and controlling method and belongs to the field of prevention and control of diseases and pests of fruit trees. For different hawthorn growth and development stages, different protective solutions are prepared in several time periods including the period before complete blossom fall, the middle ten days and the last ten days of June, the middle ten days and the last ten days of July and the middle ten days and the last ten days of August to conduct multiple times of protective sterilization spraying on hawthorn trees and achieve the purpose of effectively preventing and controlling the physalospora piricola, meanwhile physalospora piricola nose is prevented from producing pesticide resistance, and a preventing and controlling effect lasts for a long period of time.

Description

A kind of prevention and controls of hawthorn ring spot

Technical field

The invention belongs to pest and disease control of fruit trees field, specifically a kind of prevention and controls of hawthorn ring spot.

Background technology

Fruit tree ring spot also known as wheel line decayed fruit disease, scurf, wheel line brown rot and excipuliform scurf etc., it is common It is in many planting fruit-trees such as apple, pears, peach, Lee, apricot, chestnut, jujube, Malus spectabilis and general closely ripe in fruit Phase and storage period fall ill.During morbidity, scab is formed oblate or oval centered on hole skin on branches of fruit trees The bronzing scab of shape.Scab quality is hard, umbo, such as a wart-like lump, edge cracking, often Circular groove together with being organized the formation of with strong portion.In morbidity Second Year, scab center produces many black small grain points, disease Spot is gradually deepened with strong portion crack, and diseased tissues tilts such as saddle, many scabs and often connects together, and makes table Skin seems very coarse.Many trees for having just enter into fruiting period have just been covered with the sick knurl of ring spot, into outer The whole limb of tree of fruiting period and major branch have all become tertia, and some small branches are also rough, are killed tight The orchard diseased plant rate of weight is up to 100%.Also easily there is ring spot in thornbuss, conventional control ring spot method is to thank 1 week spray 80% carbendazim, 800 times of liquid, respectively sprays in mid-June, late July, August early and middle ten dayses later after spending 1 bactericide.But with the drug-fast enhancing of Target spot pathogen, along with the extraneous factors such as environment cause preventing and treating to be imitated It is really unsatisfactory, worse and worse.

The content of the invention

It is an object of the invention to provide a kind of prevention and controls of hawthorn ring spot, the method can be permanently effective Prevention and treatment thornbuss ring spot.

A kind of prevention and controls of hawthorn ring spot, comprise the following steps：

(1) in hawthorn is thanked spend first 2-5 days completely, by potassium dihydrogen phosphate, refined filtration biogas slurry, calcium chloride, bacterium more than 50% Clever wettable powder, clear water press 7:200:2:1:300 mass ratio is miscible, obtains protective liquid A, pouring root once, Germicidal solution A is diluted 1-3 times, is sprayed once on thornbuss limb；Described refined filtration biogas slurry is biogas slurry The filtrate that stoste is filtrated to get through 120 mesh；

(2) mid-June, urea, refined filtration biogas slurry, 1.1% matrine pulvis, Bordeaux mixture are pressed 4:100:1:100 Mass ratio it is miscible, obtain protective liquid B, pouring root once, and is directly sprayed once, 6 on thornbuss limb The last ten-days period moon spray once again；The configuration proportion of the Bordeaux mixture is 1：1:150；

(3) mid-July, by Pu public affairs extract, Baical Skullcap root P.E, refined filtration biogas slurry, zinc sulfate, polyvinyl alcohol, Thiophanate-methyl, clear water press 7:8:200：3:4:4:800 mass ratio is miscible, obtains protective liquid C, directly Sprayed on thornbuss limb once, late July dilutes 2-5 times and sprays again once；

(4) early August, by 50% carbendazol wettable powder, refined filtration biogas slurry, polyvinyl alcohol, thiophanate-methyl, Clear water presses 1:100:2:3:400 mass ratio is miscible, obtains protective liquid D, is directly sprayed on thornbuss limb Once, protective liquid mid-August D dilutes 4-6 times and sprays once, and late August protective liquid D dilutes 1-3 times and sprays Spill once.

Beneficial effects of the present invention：The present invention uses the policy of putting prevention first and combining prevention with control, for hawthorn not With growing period, preparing different protective liquids carries out the sterilized sprinkling of multiple protective to thornbuss, reaches wheel The purpose of line disease effectively prevention and control, while avoid Target spot pathogen developing immunity to drugs, the prevention effect duration is long.

Specific embodiment

The present invention is described in further detail with embodiment below, but is not construed as limiting the invention.
