Frequency trembler lamps and other harmless technology how to control the three most common grape pests, What are the three most common grape pests? Which is the most harmful? Here, Xiaobian to introduce:
A, colomerus:
Commonly known as felt disease, grape rust mite. In the northern area and the distribution of grapevine growing each year, the degree of loss.
<strong> (1) harm symptom:</strong>
The main harm leaves, shoots, tendrils, fruit and other parts of the serious when also can harm grape leaf stems; positive round or irregular necrotic spot.
The main leaf injury, damaged leaf blade abaxially white spots, gradually expanded, face of blade vesicular protrusions.
(2) control method:
1, to prevent the spread of seedlings. From the ward led seedlings must use hot water disinfection, first with 30-40 DEG C hot water soak for 5-7 minutes, and then 50 degrees hot water for 5-7 minutes to kill latent mite.
2, in the growing season mark plants, breeding seedling species cannot occur from plants, to prevent the spread of. The purchase of new grape seedlings or cuttings, quarantine and disinfection must be carefully.
3, found dead branches, immediately cut deep.
4, autumn vineyards completely clean. The diseased leaves collected and burned.
Two, a.lucorum:
In addition to Xinjiang, Tibet and other minority areas, the country has occurred. Mainly by sucking harm to the grape leaves and flowers shoots and tender ear. The body has the advantages of small volume, occur early, nocturnal, early damage is not obvious, easy to be ignored, often because the treatment is not timely, resulting in leaf damage, affect photosynthesis.
(1) harm symptom:
The leaves are red brown, needle size necrosis. With the growth of leaves was part of the irregular hole, and the occurrence of wrinkles.
<strong> (2) control method:</strong>
1, with clear winter garden, weeding, scrape Alice skin, eliminate a.lucorum overwintering eggs.
2, grape and cotton and vegetable intercropping, strengthen pest control of crops around the vine, thereby reducing grape pests.
3, the protection of natural enemies, such as parasitic mites, lacewings, o.sauteri and parasitoids, to reduce the number of drugs. In addition, also planting alfalfa, beans, and other crops around the spoon in the orchard.
4, sweet and sour basin. The sweet and sour liquid (brown sugar, vinegar, water 250g 500g 5kg) in the waste bottle, hanging on the tree.
5, the use of a.lucorum phototactic characteristics better than installed in the vineyard Frequency oscillation pest-killing lamp Physical trapping. Jiaduofrequencytremblergrid lamps with light, wave, color and flavor using patented technology used for distance wave, light source with specific color and odor lure adult pest lamp with beat frequency vibration of high voltage power grid contact close to pests, pest insect receiving bag into the light. For large quantity, a wide variety of pests of Lepidoptera, Coleoptera, Orthoptera, Homoptera, Hemiptera, Hymenoptera, Diptera, Lepidoptera, Dermaptera, Guangzhou Mao Chimu, Blattaria 13 to more than 1287 kinds of pests.Application of a wide range and large area.
<strong> Three, tobacco thrips:</strong>
The grape thrips tabaci, also called thrips. In China's grape has been widely distributed in recent years, the harm to the grape growing.
<strong> (1) damage symptoms:</strong>
The main use of grape flower buds and young fruit juice. Grape fruit produced at the beginning of victimization, dark brown on the fruit surface damaged spots, slightly sunken, suborbicular or strip; with the fruit development, gradually become brown, slightly elevated; after the enlargement of the crack will occur, serious when seeds exposed; small leaf injury, gray yellow spots appear, serious influence the growth and development, reduce production.
<strong> (2) prevention and control measures:</strong>
In winter 1, complete removal of field residues and leaves and host weeds, reduce overwintering insect.
2, pay attention to the protection and utilization of natural enemies. According to our preliminary investigation, many tobacco thrips species of natural enemies, common predators have stripes of thrips, thrips, broadly winged six spotted o.sauteri and kahime bugs, these enemies have certain control effect on tobacco thrips.
3, there are more blue tobacco thrips habits in 5 6 months in the pests in vineyards set the blue sticky board, killing a large number of tobacco thrips thrips and other harmful. Better than the sticky board are red, yellow, green, green, blue, purple, white, pink, gray, black etc. or custom. 1, open use, convenient use, 2 special chromatography, double trap, the effect is significant. 3, in particular, smooth non crimp, high viscosity glue waterproof, sunscreen, rain resistant, high temperature aging, durable in the temperature of 10 degrees Celsius to 70 degrees Celsius environment substrate without obvious deformation, colloid does not flow, water insoluble. In use, the same color, surface to surface and the backlight in the sunlight with no obvious color difference. Sticky board material: PP material, high strength, hardness, resistance to certain wet, double-sided adhesive, surface.
