Experience in Integrated Control of Grape Pests

1 Control techniques in dormant period (November-March) during this period, the rampant pests stopped their activities, and all kinds of pests entered the overwintering state in different states and ways, and the overwintering places were relatively hidden.

1.1 after removing the fallen leaves of grape in the orchard, remove the fallen leaves, dead branches and weeds in time, concentrate and burn them, and control the overwintering pests such as grape ten-star leaf beetle, grape two-star leafhopper, poplar leaf beetle and grape leafhopper in deciduous leaves, dead branches and weeds. 1.2 combined with pruning, the branches and shoots of diseases and insect pests were cut off thoroughly, and the expanded branches caused by grape winged moths, dead useless branches of cicadas eggs and overwintering branches of grape tiger longicorn beetles were cut, and the cut branches were taken out of the orchard for centralized treatment. 1.3 scrape off the old thick bark after the grape is unearthed, scrape off the old warped skin in time, and destroy it centrally, in order to eliminate the female adult mite of grape short beard mite overwintering in it, on this basis, spray 3-5 Bomedo stone sulfur mixture to damage Liping 1 000 times. At the same time, it is found that the egg mass of the spotted wax cicada should also be scraped off. 1.4 elimination of overwintering insects combined with grape buried in winter and unearthed in spring, orchard ploughing was carried out to eliminate overwintering insects such as grape diamondback moth, grape tiger moth, sparrow moth, grape spot moth and so on. (2) Control techniques during flowering period (April to May) at this time, the new shoots of grapes have grown rapidly, and with the gradual increase of air temperature, the pests after overwintering begin to do damage on the new shoots or leaves. The main pests in this period are grape leafhopper, grape long beard moth, spotted wax cicada, grape short beard mite and so on. Because some pests like to be harmful to the young parts and the back of leaves, the chemical control must be considerate and meticulous. 2.1 picking leaves and killing insects made use of the characteristics that the newly hatched larvae of grape ten-star leaf beetle were basically in the lower leaves, the insecticidal leaves were removed and concentrated treatment. 2.2 Light and sugar and vinegar solution trapping and killing of grape diamondback moth and sparrow diamondback moth, black light was placed in May to trap and kill overwintering adults, or sweet and sour liquid basins were set up to trap grape diamondback moth. 2.3 artificial killing of adults such as poplar leaf beetle, apple hair beetle and small blue and white beetle has the characteristics of false death, Zhang single shock, concentrated killing. 2.4 Chemical control sprayed 50% dichlorvos EC or 40% omethoate EC and other conventional agents during the peak hatching period of Cicada cicadae in early May for 1 or 2 times. At the same time, it can also treat grape short beard mites, grape leafhopper adults and some nymphs. In late May, during the peak period of the nymph of grape two-star leafhopper, 20% fenvalerate EC was sprayed with 3 000 times of fenpropathrin EC and 1 000 times of Shailiping, and it could also treat grape ten-star leaf beetle and late-onset nymphs. (3) Control techniques in fruit expansion period (June to July) when the grape ovary begins to expand and develop into berries, which is also the key period for pest control. The main pests in this period are grape leafhopper, grape short beard mite, grape diamondback moth, grape wing moth and so on. 3.1 cut off the insect branches in time to cut off the insect dung or withered branches and deal with them, so as to kill the newly hatched grape wing moth larvae and grape tiger longicorn beetles. If the branches are not cut off, the larvae can be stabbed through the wormhole with iron wire. At the same time, it can kill the adults and larvae of grape moths. 3.2 artificial hunting comes to the beginning of June, grape leaf beetle larvae have pseudo-death, and their habits can be used to kill by shock. 3.3 Light trapping and placement of black light can trap and kill grape moths, grape wing moths and adults of the family Noctuidae that suck berries. 3.4 the suitable period for chemical control of grape short beard mites is in the peak period of reproduction and damage before and after the overwintering mites have been stung but not spawned; the suitable period for the control of grape diamondback moth and grape ten-star leaf beetle is the hatching period of larvae; the suitable period for the control of grape tiger moth is the hatching period of the first generation larvae, and the suitable period for the control of grape wing moth is the peak period of adults and larvae. 4 Fruit harvest time (August to October)
