What are the characteristics of Munag grapes? What are the prevention and control methods of diseases and insect pests?

Grape is one of the common fruits in summer, with many varieties, such as green pericarp, purple pericarp, large granule, small granule, seed and seedless. Among them, Munag grape is very famous, so what are its characteristics? What are the prevention and control methods of diseases and insect pests?

What are the characteristics of Munag grapes?

Munag grape has large grains, thin skin, bright color, sweet taste, thick and crisp flesh, and can be sliced. It is a local variety with the most characteristics of fresh food, late ripening, storage and transportation in Xinjiang.

Many people know about Kerry State, but they have never been to it. Kezhou, also known as "the State of Wanshan", is located in the southern vein of Tianshan. The climate here is suitable, with natural advantages such as long light time and large temperature difference between day and night, which provides a good growth environment for forest fruit varieties such as Munag grape, fig, apricot, seabuckthorn and so on.

Second, what are the prevention and control methods of grape diseases and insect pests in Munag?

1. Grey mold

The main damage sites of grape gray mold are Corolla, spikelet pedicel, pedicel and fruit. When there is a disease in the pedicel, it will be broken by a little vibration, and when the fruit is damaged, it is easy to crack, produce gray mildew, expand and spread, which will cause the whole ear to rot.

Prevention and control measures:

(1) in the early stage of the disease, the ear of the disease should be cut off in time to prevent the disease from spreading.

(2) during the flowering period, 64% carbendazim wettable powder 750 Mel 1200 times, or DuPont Kelu and Rhizoctonia 550 Mel 750 times, Portuguese dew 1300 Mel 2200 times.

2. Tiger longicorn beetles

The grape tiger longicorn beetle mainly harms the annual female branches through the larvae, and the perennial branches are sometimes affected by insect pests. In August, adults lay eggs on the branches, and the larvae eat the new shoots. Sometimes several larvae appear on one female branch, which is eaten by segments. The damaged branches are black and easy to break, or even wither.

Prevention and control measures:

Cut off the diseased branches in the process of winter cutting, gather together and burn them, or continuously spray 82% dichlorvos EC 900x 3Mel 5 times during the adult egg period in August, egg worm kill 1300 times, insecticidal star 950Mel 1450 times, it can kill some adults and reduce the number of eggs laid.

3. Root nodule aphid

Grape nodule aphid is not only a destructive pest, but also an important quarantine object. The grape nodule aphid overwinters through the larvae on the main root and lateral root of the grape, and then starts its activity in the next spring. After feeding, it carries out parthenogenesis, that is, it lays eggs without mating and propagates for 4 mi 6 generations. Grape roots will grow nodules after the disease, the color is bright yellow, and then slowly turn brown and gradually rot.

Prevention and control measures:

(1) first of all, it is necessary to strengthen the quarantine of seedlings and prohibit the procurement of seedlings from epidemic areas.

(2) secondly, disinfect the seedlings and soil. Soak the seedlings or cuttings in 34 ℃ 42 ℃ water for 9 minutes, and then soak them in 52 ℃ hot water for 6 minutes to kill most of the pests. When carbon disulfide was injected into every square meter of soil, 37m ~ 74g of carbon disulfide could kill most root nodule aphids.

(3) at last, permethrin, cypermethrin, dimethrin and other pyrethroids can be irrigated in spring and autumn with 1600murl 3100 times in the affected areas.
