What if there are white insects in the soil where flowers are raised?
During the process of growing flowers at home, the sudden appearance of white worms in the soil is a common problem that plagues countless flower friends. These seemingly harmless little creatures actually hide a crisis. They will not only eat away at plant roots, but may also cause chain diseases. Mastering scientific identification and prevention methods is the key to protecting the healthy growth of flowers. Identification of hazard of flower soil insects and identification of white insect species The common white pests in flower soil mainly include whiteflies, root mites and grub larvae. Among them, whiteflies are 1-2 mm long and are often clustered on the back of leaves; root mites are even smaller and are mostly translucent; grub larvae are scarab larvae with a C-shaped curve. Accurate identification of insect species is a prerequisite for formulating control strategies. Analysis of hazard symptoms: At the beginning of the pest, the leaves are yellowing and wilting. As the insect population expands, the plants will experience growth stagnation and flower buds fall off. Honeydew secreted by whiteflies can induce coal pollution disease, root mites can cause root system rot, and grub larvae can directly chew fibrous roots, forming a compound damage chain. Three-dimensional prevention and control solutions Physical prevention and control measures 1. High temperature exposure: Spread the new soil and expose it for 3-5 days before use. Ultraviolet rays can kill more than 90% of the eggs. 2. Isolation and protection: Lay a pearl rock layer or river sand layer with a thickness of 3 cm on the surface of the flower soil to form a physical isolation belt 3. Adhering board assistance: Hang yellow adhering board around the plant to intercept the spread of adults. Biomedical agents are recommended to use botanical pesticides such as matrine and azadirachtin, and add 2000 times water to irrigate roots every week. Beauveria bassiana biological preparation can be used for grub, mixed with flower soil in a ratio of 1:50. Chemicals should be selected from low-toxicity products such as imidacloprid and thiamethoxam, and diluted and used strictly according to the instructions. Environmental control techniques keep the moisture of the flower soil in the range of 40-60%, and regularly loosen the soil to increase breathability. Cooperate with the application of organic fertilizers such as decomposed sheep manure to promote the reproduction of actinomycetes and form a biological barrier. The mixed substrate of coconut bran + vermiculite can be replaced in severely affected areas to fundamentally change the breeding environment for pests.
Through the trinity of "prevention-management-maintenance" prevention and control system, existing pests can not only be effectively eliminated, but also a long-term protection mechanism can be established. It is recommended to conduct monthly soil health inspections for early detection and early treatment. Remember that maintaining scientific management of cultivation substrates is the fundamental way to eliminate the breeding of soil insects.
