How do garden flowers cope with spiders?
Horticultural flowers are quite common in planting. Today, I would like to share with you how horticultural flowers deal with red spiders.
How horticultural flowers deal with red spiders:
Red spider disease has a wide range of hosts, such as rose, rhododendron, sweet-scented osmanthus, begonia, bergamot, chrysanthemum and many other flowers. When adults and nymphs absorb flower juice, the damaged leaves appear dense and small yellowish dots, which will cause withered and yellow leaves when there are a large number of them. The reproduction rate of mites is fast, and the high temperature and dry climate is beneficial to their reproduction. The insect mainly moves on the back of the leaves and spreads from the lower part of the plant to the upper part of the plant.
Control methods: weeds and withered leaves around flowers are burned centrally, and new high-fat film is applied in time, which can automatically form a polymer protective film invisible to the naked eye, and optimize the quality of water absorption, air permeability and light transmission of plants. Block disease and insect predation signals and weaken the transmission media, resist and defend against natural environmental disasters. In the early stage of the disease, targeted agents should be applied in time, and insecticides must be used together with new high lipid membrane to improve the control effect and reduce the amount of pesticides. Usually should pay attention to observation, once found that there is a red spider harm, should spray prevention and control.
