Rice pest control primarily focuses on managing aphids, rice planthoppers, rice blast, sheath blight, and rice gall midge. The strategy emphasizes integrated pest management (IPM), which combines agricultural practices with the responsible use of pesticides. By leveraging natural predators and adopting targeted prevention methods, the goal is to enhance overall control effectiveness while minimizing chemical pesticide use. This approach ensures economic viability, safety, and long-term sustainability in rice production.
Preventive measures are crucial in areas where *Sphaeroteca sanguinea* and *Pseudocercosporella utilis* are prevalent. Farmers should carefully plan crop arrangements, reduce mixed planting areas, and manage planting times to avoid local infestations. Early field soaking and reduced wintering periods help lower pest survival rates. Selecting resistant rice varieties is also key to reducing disease vulnerability. Seed disinfection and soil treatment in dry seedling fields can prevent seedling diseases, while proper water and fertilizer management improve plant health and resistance to pests and diseases.
When it comes to pesticide use, it’s essential to follow forecasts and field surveys. A small area (such as seedbeds) should be prioritized for early intervention, ensuring better control across larger fields. Choosing the right pesticide based on specific pests is critical. For example, **tricyclazole** and **chlorothalonil** are effective against rice blast, while **benzothiadiazole** works well for sheath blight. For bacterial leaf streak and bacterial blight, **streptomycin** or **kasugamycin** may be used. For diseases like rice smut, cloud disease, and sheath rot, **40% scutellariae** or **pyridine** can be applied. Insect pests such as planthoppers can be controlled using **Bt** or **pyridaben**, while **Yi Shufeng** is effective against rice gall midge.
Timing is vital for effective control. Rice blast should be managed when 10% of the plants break, and rice smut should be addressed 3–5 days before this stage. For rice gall midge, applications should occur 5 days after sowing or 5–7 days after transplanting.
It is strictly prohibited to use pyrethroids or their mixtures in paddy fields. Similarly, highly toxic pesticides like **methamidophos** must not be used in the later stages of rice growth. Organophosphorus insecticides like **triterpenoids** should be used cautiously in the early growth stages to avoid triggering outbreaks of rice leafhoppers later in the season.
By following these guidelines, farmers can achieve more sustainable and efficient pest management, leading to healthier crops and a safer environment.
