Rice planthopper, also known as rice floating dust, belongs to the order Homoptera, and is a important migratory pest. Mainly harmful to rice, corn, wheat, sorghum, sugar cane, whitening and so on. The insect pests occur in all rice producing areas in China, among which the southern rice area is dominated by brown planthopper, followed by the brown planthopper and whitebacked planthopper, while the most common in the northeast is the gray planthopper and whitebacked planthopper.

Hazard symptoms of rice planthopper:

Rice planthoppers use adult nymphs to suck rice sap with sucking mouthparts to cause damage. At the same time, the toxins secreted by the toxins cause rice poisoning to wither and eventually lead to rice death. Because both the gray planthopper and the white-backed planthopper are incomplete metamorphosis insects, both adults and nymphs suck the rice juice with a sucking mouthparts as a hazard, and most of them gather in the middle and lower parts of the rice plants to feed the stalks. With leaves.

The rice stalks affected by the adult stage will have some irregular brown spots on the surface, and the leaves will gradually turn yellow from bottom to top. The whole plant grows slowly and becomes shorter. At the same time, some rice is not completely headed, even if the heading is mostly white ear, the seed setting rate is very low. The lower part of the more severely affected rice plants gradually darkened, resulting in the collapse of the rot and death. If the insects occur early and the number of adults is large, the ovipositor will cut the leaves and stems of the seedlings when the rice planthoppers lay eggs, causing the plants to lose water. In severe cases, the rice seedlings will die and die.

Rice paddy plants can be controlled by the following methods:

1, selection of resistant varieties. The selection of resistant varieties is the most economical and effective way to control rice planthoppers. At present, many high-yield and insect-resistant varieties with utilization value have been cultivated and screened in China, and localities can choose according to local conditions.

2. Strengthen the management of fertilizer and water. In order to enhance the disease resistance of rice, rational fertilization is achieved. On the basis of applying the base fertilizer, the topdressing should be carried out in a timely manner, but it is necessary to pay attention to the application amount of nitrogen fertilizer, and not to be excessive, in order to avoid the long and late maturity of the rice plant. Control the rational mix of nitrogen, phosphorus and potassium to achieve a combination of control and control. It is necessary to implement scientific irrigation, to achieve irrigation and drainage freely, shallow water and dip irrigation, alternating wet and dry, timely drying the field, and prevent long-term water accumulation in rice fields.

3. Protect and use natural enemies. For example, pesticides that reduce toxicity such as methamidophos and have a killing effect on natural enemies, use selective agents, adjust the time of medication, reduce the number of medications, to avoid a large number of killing natural enemies, and play a natural enemy control role.

4, chemical control, the use of Debao can effectively prevent and cure.
