After the drought of flower crops or legume crops due to lack of soil moisture, the roots of the plants are not well grown, and it is difficult to fully and effectively absorb the water and fertilizers. It is prone to the growth of the above-ground parts of the plants weakening and yellowing. In severe cases, the lower branches and leaves of the plants and even the whole plant may be deficient in water. Wilting dehydration and de-fertilization; under conditions of insufficient soil moisture in the plant, the soil is not easily dissolved by the fertilizer and is absorbed by the plant, resulting in excess accumulation and remnant in the soil, followed by salt hazards; cell growth is not affected by water Affected, the physiological state of the plant body is poor, and it can easily be infected by some bacteria. At the same time, under relatively hot and dry climate conditions, it is often beneficial to the development of some pests, breeding and invading plants, and eventually causing drought and pests and coexistence of the unbearable situation.
Commonly used in dry heat environment, the common pests that have harmful effects on crops are aphids, leafhoppers, beet armyworms, thrips, whiteflies and other pests. Common diseases that have a detrimental effect on crops are virus disease and powdery mildew. , moldy tobacco, blight, blight, and lack of disease (physiological disease). Therefore, we should do a good job of comprehensive prevention and control of pests and diseases of flower crops or legume crops against the pests and diseases that are easy to see in dry and hot environments. In addition, fertilizer types that are easily soluble should also be selected and applied in small amounts at the right time.
Prevention and control technology measures can be carried out in accordance with the characteristics and laws of the hazards of the disease, according to the conventional control methods of aphids, leafhoppers, beet armyworm, thrips, whitefly, powdery mildew, blight, blight, prepared in advance Pesticides required for the prevention and control of pests and diseases can be controlled in a timely and effective manner.
The overall responsibility is: to do a good job in the cleanliness and sanitation in and around the shed, and to remove the weeds and insecticides in the greenhouse. At the same time, do a good job of routine repairs and maintenance of greenhouses, doors and windows, and insect nets to protect or enhance the physical pest and insect resistance of the greenhouses. Carry out serious weekly inspections, observe carefully, and do regular chemical pest control and insecticidal and plant protection work; once an individual or a small number of diseased plants are found, they should be immediately removed, and at the same time conduct comprehensive pesticide control and pesticide application. Prevention and control of pests and pesticides should be observed to follow the locusts, leafhoppers, thrips, and whiteflies are piercing and sucking mouthparts, the hazard is to draw plant sap; prevention and treatment of drugs should use stomach poison pesticides. Spodoptera exigua is a chewing mouthpart, and the hazard is to take all parts of the plant. Anti-drugs should be used for pesticide contact pesticides.
Specific pest and disease control drugs have certain differences, as listed below:
