Grape black pox is also called scab. Grape leaves, cobs, fruit stems, tendrils, new shoots, fruits and other young parts can be affected. The affected part has brown spots, and the leaves, young shoots, tendrils, etc. are twisted and shrunk, and the young fruit is deformed. The disease occurs before and after germination of early spring grapes, and the rainy years, poor orchard drainage, extensive management, and weak tree disease are severe.
Before the grape leaf to fruit coloring, control, spray once every 10-15 days; before flowering and Xiehua 70%-80%, even spray 2 times. Pharmacy can be 0.5% lime half amount Bordeaux mixture, 50% carbendazim WP 800 times solution, Dasheng m-45 800-1000 times solution, 80% spray WP 800 times solution, 5% bacteria poison water agent 1000 Double liquid spray treatment.
Second, white rot
Grape white rot is also called rot disease. The grape leaves are susceptible to the near-round brownish-colored lesions, which are inconspicuous concentric striate, and the leaves are dry and fall off later. The lower part of the plant is close to the ground, and the cob or small fruit stalk is brown and water-immersed. It becomes soft and rot in the later stage, and it is easy to fall off. The fruit is softened with browning. Branches are easy to occur in the lesions, the cortex is separated from the xylem, longitudinally split, the fibers are chaotic, the branches are physiologically blocked, and the branches are gradually dead.
Before the flowering of the grapes, the mulch under the trunk is very effective. In the growing season, the heart is picked up in time, and the auxiliary tips are trimmed to make it ventilate and light. If the orchard is drained and dehumidified, the distance between the ear and the ground surface can be appropriately increased, which can reduce the infection of the pathogen and reduce the incidence. In addition, the initial stage of the disease can be selected from 50% carbendazim 800-1000 times solution, 75% chlorothalonil 600 times solution, 50% Fumei double 600 times solution, 80% ethyl phosphine aluminum 800 times solution and other rotation spray control, 10-15d Spray once, even spray 3-5 times, the effect is good.
Third, anthrax
Grape anthracnose is also called late rot. Mainly harmful to the coloring or near ripe fruit. The surface of the fruit is affected by the large brown round spots of the beans, and the depressions produce small black spots arranged in a wheel pattern. In severe cases, the fruit is soft and rot, gradually losing water and shrinking or becoming a stiff fruit. Rainy summers or management of extensive orchard disease occur heavily.
Before the fruit is inflated, the bagging technique is more effective, but the cost is higher. Spraying 5% of the bactericidal water-clearing agent 200-300 times before the germination of the grapes to eliminate the pathogens on the branches, can reduce the occurrence of diseases. It is also possible to spray 50% carbendazim 800 times solution, or 70% dexamethasone 600 times solution, or anthrax fumei 500-800 times solution, or 80% spray 800 times solution, or Dasheng m-45 600 before fruit coloring. - 800 times liquid for prevention. Spray once every 10-15 days, even spray 2-3 times.
Fourth, powdery mildew
Grape leaves, new shoots, tendrils, fruits, etc. can be damaged, and the surface of the damaged tissue has a pale white powdery mildew layer. The young fruit is atrophied and shedding, and the large fruit is damaged. There are brown spots under the fruit surface layer, and the fruit is hardened or longitudinally cracked. High temperature, dry and cloudy weather is conducive to the occurrence and prevalence of this disease. Excessive cultivation, excessive application of nitrogen fertilizer, vine leaves and other beneficial diseases occur.
It is better to spray 3 to 5 waves of sulphur sulphur mixture before germination. In the early stage of the disease, spray 1-2 times 20% powder rust 1000-1500 times solution, or 70% methyl thiophanate 800-1000 times solution, or 50% sulfur suspension agent 300-400 times solution.
5. Downy mildew
The leaves of the grape leaves have pale yellow water-immersed lesions, and the back has gray-white frosty mildew. The fruit and fruit stems are covered with hoarfrost, the fruit stems brown and necrotic, and the shoulders of the fruit become brown and even fall off. Low temperature and rain, heavy fog, and weak plants are conducive to the occurrence and prevalence of diseases.
In the early stage of the disease, spray 1:0.7:200 times Bordeaux mixture, or 25% toxic mycelium 500 times solution, or 40% ethyl phosphine aluminum 300 times solution, or 40% carbendazim 1500 times solution, or 64% Anti-virus 矾 500-800 times liquid, or 50% bacteriostatic 500 times liquid spray control, 7-10d spray once, even spray 3-4 times.
