Family flower pests and diseases prevention and control technology

First, choose disease-free and disease-resistant varieties. Choosing flowers without pests and diseases is an important part of controlling pests and diseases. It is strictly forbidden to bring flowers with pests and diseases into the family, so as not to affect the growth of the original flowers. Flowers have been bred into varieties with strong disease resistance (such as aster resistant to blight), and selection of disease-resistant varieties is the most economical and effective way to control pests and diseases.

Second, deep turn, soil change, soil. Family indoor cultivation of flowers, deep plowing may be lurking in the soil in pots larvae, pupae, eggs, etc. turn to the ground by other natural factors, such as the effects of light, temperature, humidity, and increased mortality, but also can be Artificial killing. The soil can bury the pathogens and residual leaves in the shallow soil into the deep soil layer, causing it to lose its vitality and increase soil nutrients. Change the soil, you can change the diseased soil in the flower pot to improve the soil fertility, which is conducive to the healthy growth of the flower.

Third, a reasonable amount of watering. Reasonable fertilization means that the proportion of nitrogen, phosphorus and potassium is appropriate, to prevent excessive application of nitrogen, causing long leaves and leaves, and susceptible to pests and diseases. At the same time, attention should be paid to the application of fully decomposed human waste water and organic fertilizer. Watering should be timely and appropriate, too much, so that the flowerpot soil is in anoxic state, easy to rotten roots, root development is blocked; too little, affecting flower growth, easy yellow leaves, withered.

Fourth, timely weeding, pruning in due course. Weeds not only compete with flowers for nutrients, but also affect ventilation and ventilation, hinder growth, affect viewing, and are also places where germs and pests multiply. Timely weeding, should create suitable environmental conditions and reduce the incidence of non-infectious disease. The flowers and trees are trimmed, and the diseased branches, dead branches and residual branches are cut off, and the eggs, larvae and adults on the branches are eliminated, and the weeds, diseased branches and the damaged plants are removed in time to avoid secondary infection and reduce the number of pathogenic bacteria and pests.

Fifth, physical control, combination of prevention and control. Using a certain tropism of the pest (such as phototaxis), suspended animation or other characteristics, artificial trapping and killing, killing pests and diseases. For flower plant has been infected, due to family conditions, there is a risk of poisoning problems and environmental pollution, should grasp the opportunity, the right medicine, the amount of spraying, to prevent injury and plant allergies. Plant pesticides that are less polluting to the environment can also be used. If you use a cigarette to put 10 times of water in the water for a day and night, filter out the smoke residue, add 10-15 times of water and a small amount of neutral detergent before spraying, spray immediately after spraying, can control the thrips, leaf curlers, and dive. A variety of pests such as leafhoppers.
