Problems solved by technology

The grape leafhopper is a serious hazard. Its secretions pollute the fruit surface and make the grapes lose their commercial value. Their adults and nymphs suck the grape juice, causing the tree to decline rapidly, the fruit shrivels, and the quality declines, causing serious economic losses. kind of virus

Embodiment 1

[0025] Embodiment one: the method for ecological control grape leafhopper

[0026] 1. Use yellow boards to trap and kill overwintering adults. Use them after the grape pier is opened. Hang the yellow boards on the first iron wire near the root of the rack surface, parallel to the direction of the wires. The dosage is 300 pieces per hectare. The control time is April late;

[0027] 2. Combined with the prediction results, when the population density reaches 12 / 100 nets, the first generation of nymphs will be controlled, and the control time will be in late May, mainly using chemical control, such as 2.5% Caixi 1500 times or diflubenzuron, etc.;

[0028] 3. Carry out autumn pruning and summer pruning. According to the characteristics of the variety, the vegetative branches before and after flowering should be left with vegetative branches for small ear varieties below 500g; for large ear varieties with more than 500g, one vegetative branch should be left for each ear to keep the...

Embodiment 2

[0035] Embodiment two: the method for ecological control grape leafhopper

[0036]1. Use yellow boards to trap and kill overwintering adults. Use them after the grape pier is opened. Hang the yellow boards on the second iron wire near the root of the rack surface, parallel to the direction of the wires. The dosage is 450 yuan per hectare. The control time is early May. ;

[0037] 2. Combined with the prediction results, when the population density reaches 12 / 100 nets, the first generation of nymphs will be controlled, and the control time will be in the first ten days of June. Chemical control is mainly used, such as 2.5% Caixi 1500 times or diflubenzuron, etc.;

[0038] 3. Carry out autumn pruning and summer pruning. According to the characteristics of the variety, the vegetative branches before and after flowering should be left with vegetative branches for small ear varieties below 500g; two vegetative branches should be reserved for each ear of large ear varieties above 50...

Embodiment 3

[0045] Embodiment three: the method for ecological control grape leafhopper

[0046] 1. Use yellow boards to trap and kill overwintering adults. Use them after the grape pier is opened. Hang the yellow boards on the first or second iron wires near the roots on the rack surface, parallel to the direction of the wires. The dosage is 400 pieces per hectare, and the control time is 4 Late month to early May;

[0047] 2. Combined with the prediction results, when the insect population density reaches 12 / 100 nets, the first generation of nymphs will be controlled, and the control time will be from late May to early June. Chemical control is mainly used, and 2.5% Caixi is used to 1500 times or kill young Urea, etc.;

[0048] 3. Carry out autumn pruning and summer pruning. According to the characteristics of the variety, the vegetative branches before and after flowering should leave vegetative branches for small ear varieties below 500g; leave 1-2 vegetative branches for each ear of...

Abstract

The invention discloses an integrated method for biologically preventing grape leafhoppers. The method comprises the following steps: adopting yellow plates to lure and kill wintering adult worms after a grape pier is dug; hanging the yellow plates in parallel to a first iron wire or a second iron wire of a trellis surface close to the root, wherein 300-400 yellow plates are used in each hectare;preventing first-generation nymphs when the population density reaches 12 / 100 mesh; preventing the grape leafhoppers by adopting medicaments, i.e. 1,500 times of 2.5 percent of success or chlorbenzuron; remaining vegetative shoots of small fruit ears below 500g according to variety characteristics before and after flowering; remaining 1-2 vegetative shoots of each larger fruit ear over 500g to keep favorable ventilation and photopermeability of the trellis surface and lessen spotted leafhopper hazards; applying decomposed organic fertilizer with the concentration of 2-3 tons / 667m<2> in autumn;and applying the fertilizer for 2-3 times in the whole growth period to improve the plant resistance. The invention provides an integrated biological prevention method for comprehensively and biologically preventing and controlling the grape leafhoppers below an economic threshold value.

Description

field of invention [0001] The invention relates to the field of ecological control, in particular to the field of an integrated method for ecological control of grape leafhopper. Background technique [0002] Grape is a fruit produced and consumed worldwide. There are 89 countries and regions producing grapes in the world. China's grape industry is in a period of rapid development, and its area and output are increasing year by year. At present, the grape industry is developed on the basis of traditional cultivation and processing models. There are many problems in industrial development, extensive cultivation management, and the occurrence of diseases and insect pests. aggravated. In particular, the large-scale harm of leafhoppers has made it difficult for Xinjiang table grapes, raisins and wines to compete in the international market in terms of quantity and quality, and has seriously restricted the development of the grape industry. [0003] The grape leafhopper Erythro...
