Curing young people to control their use

Cockroaches are the larvae of chafers, and are the major underground pests on dry crops such as soybeans, corn, peanuts, and sweet potatoes, which endanger seedlings, crop roots, and pods, resulting in varying degrees of yield loss.

Like other pests, younger crickets have weaker drug resistance and better control of medications; older crickets have stronger resistance and are less likely to be killed. Therefore, the control of earthworms should be based on pests and disease monitoring, control in the hatching of eggs and young larvae (usually in late July to early August) spraying, production often farmers until the crop shows signs of yellow withering and other symptoms Only medication, prevention and control lag, the effect is poor.

At present, the main pesticides used for the control of earthworms are phoxim and chlorpyrifos. The main application method is to irrigate and spread poisonous soil. For example, 48% chlorpyrifos emulsifiable concentrate 250ml or 50% phoxim EC 300ml water plus 800kg per acre to irrigate root; use 3% phoxim granules per acre 2-2.5 Kg or 48% of chlorpyrifos EC 200 ml mixed with 25 kg of dry fine soil, the ditch applied to the plant roots in the soil. Earthworms have a habit of rising and falling vertically with the soil moisture content. When the soil moisture content is high, it is close to the ground and the soil is far from the ground when it is dry. Therefore, it is very important for the drug to fully penetrate the site where the pests are located. Toxic soil or granules are best to be sprayed before the rain or after the rain. If the weather is dry and it does not rain, it is better to apply water first to drought and then spread the medicine. Otherwise, the effect of increasing the dose by two times is also very poor.

According to tests by Liu Shuntong and others of the Luoyang Academy of Agricultural Sciences, chlorantraniliprole also has better efficacy against earthworms. Compared with chlorpyrifos, it has the advantages of low toxicity, low water consumption, low labor intensity, and high control efficiency. It is recommended that 35% of chlorantraniliprole dispersible granules be used in the production to control peanut pods. The dosage per acre should be 15-21 g. It is advisable to increase the amount of water when used, which can make the medicine better with peanut roots. The contact is more conducive to the conduction of the drug in the plant body and plays a more ideal control effect.
