Flower whitefly control
Whitefly is a white-tailed insect of the family Tetrandidae. It is 0.95-1.4 mm in length and has wings and white wax in its wings.
Whitefly can cause chlorosis, yellowing, wilting, and transmission of viral diseases in affected leaves. In addition, whitefly also secretes honeydew, blocking plant pores and affecting photosynthesis. In severe cases, flowers cannot grow normally. Prevention measures are as follows.
1. In the growing season, whiteflies are controlled in time for flower growth, and spraying with 10% Puercitrin EC at 1000 times can inhibit adult oviposition and nymph hatching. It can also be used as a 2.5% enemy to kill 2000 times liquid spray, which has a good control effect on various insect states. Spraying should be carried out when there are few adult moths in the morning and in the evening. Spray the front of the leaf and spray the back of the leaf.
2. The yellow plate is trapped with a transparent wide tape, and the plastic surface is fixed outwards on a yellow cardboard or board, and is hung near the damaged plant, which can seduce whitefly adults and also kill winged aphids. After sticking, change the tape.
3. Avoid cross-infection. Avoid planting of vegetables and crops that are susceptible to whitefly, such as cucumbers, eggplants, tomatoes, beans, etc., near the flowerbeds. Plant crucifer crops. Flowers that are susceptible to whitefly are not placed together. In the nursery and nursery of flowers, no insect source should be selected, and scion and cuttings should be selected to select plants without pests.
