Hazards of peanut underground pests and common control measures
Peanuts are easy to grow, and it is not easy to grow peanuts; general production is easy to achieve, but to break through high yields and obtain good economic benefits, we must pay attention to all aspects of high-yield planting techniques. Among them, underground pests eat peanut roots and peanut young fruits in the ground, which not only has a long period of damage but also has serious damages. Prevention and control of underground pests is a necessary part of high-yield peanuts and must be taken seriously. Here we talk about the underground pests of peanuts and talk about the hazards and common prevention methods.
The most important underground pests that harm peanuts are cockroaches, in addition to various underground pests such as tigers, crickets, and golden worms. Because underground pests are often underground, they are concealed and difficult to control. Do not see the prevention and control after the hazard, then it will cost a lot of time and effort, and the effectiveness is poor. Therefore, it is necessary to take precautionary measures
Now introduce several mainstream prevention methods:
1. Application of granules: Mix fine soil or fertilizer evenly when planting. The chlorpyrifos and phoxim particles found on the market. At present, 10% and 15% of chlorpyrifos granules are commonly used. For example, 10% of the enemy, 15% of the Sasdan and the high ground. The main peanut producing areas have been controlled by this method before 2011. It may be due to laborious or uneven spreading, cost, and control effects. The market in this way is shrinking.
2. Seed coating: Because of its convenience and high efficiency, it is easy to add excellent fungicides, control root rot and stem rot in seedling stage, and gradually use it after 2008, which has become the most common way on the market. At present, peanut coatings are mainly divided into two major classes of imidacloprid series and chlorpyrifos series. Due to the mixed colors on the market, it is necessary to choose a product with high safety, and it must be a high-efficiency dosage form specially used for seed coating such as suspension seed coating agent, microcapsule suspension agent and seed treatment dispersible powder. The imidacloprid series can also effectively control the damage of aphids and stimulate the growth of plant roots. Common imidacloprid series such as Gao Qiao + Wei Fu, Feng Qi suit, etc.; chlorpyrifos series such as Hu Feng, Jia Tian Jia Sheng and so on.
3. Medicine and fertilizer: As a new way of prevention and control in the past two years, due to its convenience, it has also achieved a certain market position. At present, if you want to achieve the desired control effect, the cost performance and duration are two problems that have to be solved. In some markets, the market is not bad. For this market, it is not long, and there is not much evaluation.
Tip: Regardless of which control measures are adopted, the hazards of root disease at the seedling stage should not be neglected, especially in the main peanut producing areas, planting in successive years, and the accumulation of germs in the soil, leading to many late stages. As the saying goes, there is no money for the money. Buying seedlings, it is recommended to add excellent fungicides to prevent root rot and stem rot in seedling stage.
