Abstract

The invention provides a prevention and treatment method for anthrachose of grapes which is characterized by comprising following steps:1. a mixed solution of 0.3%-0.5% sodium pentachlorophenate and 4-grade lime sulphur is sprayed before germination; first chemical spray is performed during growing period when new shoot are as long as 15cm, chemical spray is performed 3 to 5 days before flowering and 3 to 5 days after fading; chemical spray is performed once every half month from young fruit stage and 3 to 5 times of chemical spray is continuously performed, chemical spray is performed once every 7 to 10 days in rainy days; 2. diseased ears and diseased fruits are removed and picked up during growing period, and fallen leaves and branches are cleaned up; diseased branches, diseased leaves, diseased fruits and aged bark in trunks and veins are cleaned up after fruit harvest and burned concentratedly; 3. seedlings are soaked in 3% to 5% cupric sulfate solution for 3 to 5min before plantation and then disinfection is performed; drainage ditches are dug around the vineyard and among rows. The prevention and treatment method for anthrachose of grapes of the invention is convenient and easy to perform and can effectively increase the output and quality of grapes, and is conducive to a wide range of promotion and application.

Description

The prevention and controls of grapevine anthracnose

Technical field

The present invention relates to the prevention and controls of crop technical field, more particularly, to grapevine anthracnose.

Background technology

Grapevine anthracnose is shot hole again, is one of Major Diseases of Fructus Vitis viniferae.In early April high temperature and humidity weather, be conducive to the generation of Fructus Vitis viniferae Semen sojae atricolor disease；In 5 months, the last ten-days period to early June be morbidity the Sheng phase.The light green color part of children of main harm plant, causes the yield and quality of Fructus Vitis viniferae to reduce, causes larger economic loss to Fructus Vitis viniferae Producer.

Occurrence regularity: pathogenic bacteria is mainly hidden with mycelium and survives the winter in the tissues such as climing, the sick tip of disease, produces new conidium on the 2nd year, propagates by means of wind and rain, after invading plant, mycelia spreads under epidermis between 4, May.Form aceravlus in sick portion later, break through epidermis, in the case of high humidity, constantly produce conidium, carry out superinfection.Mycelial growth temperature scope 10-40 DEG C, generally 6-12 days incubation period, young sprout and spire easy infection, its incubation period is also shorter.Spring and early summer rainy high humidity are conducive to conidial formation, propagation and sprout intrusion；Meanwhile, rainy high humidity, causes shooting up of host tissue again, and therefore disease occurs seriously.

The young tender parts and petiole, cob, fruit stem etc. such as the young fruit of anthrachose of grape harm Fructus Vitis viniferae, tender leaf, tender tip, tendril.When young fruit is first killed, there is rotund lividus stigma in fruit face, gradually expand later, become scab, the dark violet brown in edge, central light brown or canescence, slightly concave sunken, above has black point；The hardening of later stage scab or cracking, disease fruit can not be grown up, and color is green, the hard sour in the mouth of matter, loses edibility.When spire vein is killed, assume polygon stigma, part of damage stops growing, cause leaf-shrinkage deformity, there is density anisodiametric brown circle stigma in the blade killed initial stage, scab edge is in crineous, central light brown or canescence later, the gradually withered perforation of later stage scab.When tender tip, tendril, petiole, cob, fruit stem are killed, initially assume the oblong scab of puce, edge color and luster is gradually deep later, in taupe, central authorities are slightly concave to be fallen into, and when serious, scab is connected, and the sick tip stops growing, and atrophy is dried up.

Content of the invention

It is an object of the invention to provide the prevention and controls of effect is significant, grapevine anthracnose easy to spread.

For realizing the above-mentioned purpose of the present invention, the present invention provides the prevention and controls of grapevine anthracnose, including.

Method 1, the front spray 0.3%-0.5% penta sodium pentachlorophenate that germinates add 4 degree of lime sulfur mixed liquors；Trophophase sprays for the first time when young sprout is up to 15cm, spends medicine of each spray in latter 3-5 days with thanking before blooming；Start to spray once every two weeks from young fruit period, continuously spray 3-5 time, meet overcast and rainy spray and shorten to spray in 7-10 days once interval time.

Described medicament is that 180-220 times of Calx half measures formula Bordeaux mixture, 800-1000 times of Tobe body fluid, 50% move back mattress spy's 800-1000 times of liquid of wettable powder, 65% 500-600 times of liquid of Zineb wettable powder one or more.

Method 2, trophophase are extractd and are picked up the sick fringe only set, disease fruit, clean the field residual branch of fallen leaves；After fruit harvesting, the Lao Pi in sick branch, sick leaf, disease fruit and trunk main stem is removed, concentration is burnt.

The copper-bath adopting 3%-5% before method 3, seedling planting soaks 3-5min, disinfection；Surrounding in vineyard and the ditch that in the ranks begins to rehearse, the deep 70-100cm in described gutter, wide 50-60cm.

Compared with prior art beneficial effects of the present invention.

The prevention and controls of the grapevine anthracnose that the present invention provides, occurrence regularity according to grapevine anthracnose and harmful characteristics, targetedly take prevention and controls, can effectively improve the yield and quality of Fructus Vitis viniferae, and the prevention and controls of the present invention are convenient and easy, are conducive to promoting on a large scale and apply.

Specific embodiment

Further describe the present invention with reference to specific embodiment.

Embodiment 1.

The present embodiment 1 provides the prevention and controls of grapevine anthracnose, including.

Method 1, front spray 0.5% penta sodium pentachlorophenate that germinates add 4 degree of lime sulfur mixed liquors, and to root out the pathogenic bacteria that survives the winter, spraying is comprehensively thoughtful；Trophophase sprays for the first time when young sprout is up to 15cm, spends medicine of each spray in latter 4 days with thanking before blooming；Start to spray once every two weeks from young fruit period, continuous 3 controllable harm of spray, meet overcast and rainy spray and shorten to spray in 10 days once interval time.

Described medicament is that 220 times of Calx half measure formula Bordeaux mixture, 1000 times of Tobe body fluid, 50% move back mattress spy's 900 times of liquid of wettable powder, 65% 600 times of liquid of Zineb wettable powder one or more.

Method 2, trophophase are extractd and are picked up the sick fringe only set, disease fruit, clean the field residual branch of fallen leaves；After fruit harvesting, the Lao Pi in sick branch, sick leaf, disease fruit and trunk main stem is removed, concentration is burnt, to eliminate the pathogenic bacteria that survives the winter.This be due to anthrachose of grape First aggression essentially from the mycelium survived the winter on invalid body it is therefore desirable to wipe out the disease fruit of disease branch top and remaining, thoroughly remove deadwood in orchard, fallen leaves, decayed fruit etc., concentration is burnt.
