In autumn, the grape grows into the nutrient accumulation stage. Management can not be ignored, otherwise it will affect the bud differentiation and fruit setting in the coming year. Grapevine leafhoppers are the most serious from September to October, and often cause defoliation, affecting the growth of grapes in the following year.
Hazard characteristics The grape leafhoppers are divided into two yellow leafhoppers and grape leafhoppers, which cause harm to apples, pears, kiwifruit and other crops in addition to harming the grapes. Leafhoppers use adult worms and weak insects to collect leaf juice on the back of leaves. Hazardous symptoms begin with the lower leaves and inner culm of the vine, gradually spreading to the upper part and the outer part. The leaves appear small gray spots, resulting in premature leaf decay, followed by development of the entire leaf surface, resulting in dehydration and charring of leaves, resulting in early defoliation, affecting leaf photosynthesis. The role and accumulation of organic matter in the tree caused the ear not to develop normally, and the fruit was susceptible to wilting and shedding, affecting the current year and the output in the coming year.
Insect causes 1. There are many leafhoppers in the grapevine, but in order to control pests, part of the fruit growers will not hesitate to increase the amount and frequency of pesticide use, resulting in a reduction in natural enemies of leafhoppers and rapid propagation of leafhoppers. 2. The closed vineyards are poorly ventilated and wet, causing many weeds in the vineyard and in the ground, creating favorable conditions for the growth and reproduction of leafhoppers. 3. The dry branches and dead leaves could not be cleaned up timely after fruit picking, which caused the overwintering adults to be eliminated in time, resulting in a large number of leafhoppers in the following year. 4. In recent years, the rapid temperature rise in spring has caused early occurrence of leaf aphid pests and a long period of time. In autumn, the temperature is high, and it is easy for the autumn crickets to safely pass through the winter. Especially in the rainy years, it is more conducive to the growth and breeding of autumn crickets, and the degree of damage is increased.
Prevention
1. Strengthen the management of grape growing period, diligently cultivating, reasonably pruning, pruning, timely picking the heart, finishing leggy branches, preventing the concealment of orchards, and improving ventilation conditions.
2. In the autumn, timely removal of rotten fruit, dead branches and dead leaves in the orchard will result in concentrated burning.
3. Leafhopper has a strong yellowing potential. It can be used on both sides of the yellow board to apply oil from stick insects. It is hung on the grape vines and the yellow board is separated by 5 meters. After the insects are full, they are promptly removed and replaced.
4. Ye Yan has a certain degree of phototaxis, which can be trapped in the vineyard by hanging solar traps.
5. Protect and make good use of natural enemies and maximize the use of natural enemies to control the grape leafhoppers.
6. Focus on the prevention of first-generation larvae from May to June and adult worms in September and October to deciduous vines. Can be used net WP, fenvalerate EC, farmland EC and other agents spray carefully, spray the main part of the leaves on the back of the grape leaf lice have a good prevention and control.
