Key Technical Points for Integrated Control of Rice Diseases, Insect Pests, Weeds and Rodents

1. Suitable areas: all rice-growing areas in Guangdong Province. The rodent control technology is suitable for controlling house mice in agriculture, forestry, livestock and poultry farming, and urban areas of Guangdong Province.

2. Key technical points for rice disease and insect pest control:

(1) Agricultural control: A. Select disease- and insect-resistant, high-yielding, high-quality varieties. B. Sow and transplant at the appropriate time. C. Rational close planting and fertilization. For seedling throwing, 40 trays per mu (560 holes) is appropriate; for transplanted fields, about 20,000 hills per mu (6X5 cun), that is, about 80,000-100,000 seedlings, is appropriate. For basal fertilizer, it is recommended to apply more organic fertilizer; according to soil fertility and yield, apply an appropriate amount of nitrogen fertilizer in the early and middle stages (about 10 kg of pure nitrogen per mu), and increase the application of phosphorus and potassium fertilizers. D. Rational irrigation and drainage, and timely exposure and sunning of the fields.

(2) Protect and utilize natural enemies. Select highly effective, low-toxicity pesticides, and prohibit the use of pesticides that are highly toxic, leave high residues, and kill large numbers of natural enemies.

(3) Adopt correct pesticide application measures. Apply pesticides intensively at the seedling stage, treat the seedling fields, and protect the main fields. In the middle stage, apply pesticides appropriately according to disease and insect conditions. At the full heading stage, attention should be paid to controlling neck blast and glume blight.
