Abstract

The invention relates to farm chemical for controlling pests of rice, which consists of the following compositions by weight percent: 6 percent to 10 percent of validamycin A, 1 percent to 3 percent of fipronil, 50 percent to 60 percent of soluble starch, 10 percent to 15 percent of calcium carbonate, 1 percent to 3 percent of sodium starch glycolate and water. The farm chemical for controlling the pests of rice is compounded farm chemical, and not only can effectively control the rice sheath blight, but also is free from causing unfavorable influence on the environment because of less dose. In addition, the cost is low, and since the farm chemical contains multiple compositions having a protecting effect on the soil, the long-term use of the farm chemical is free from hardening the soil.

Description

Technical field [0001] The invention belongs to the technical field of pesticides, and particularly relates to a pesticide for preventing and curing rice diseases and insects. Background technique [0002] Rice sheath blight is one of the main diseases of rice. The occurrence of this disease is very common. It can occur from the seedling stage to the earing stage. The most serious damage is from the tillering stage to the heading stage. It mainly damages the leaf sheath, followed by leaves and Ear department. The symptom is that the disease first produces small dark green water-stain-like spots near the water surface of the leaf sheath, expands into an oval shape, and finally takes a moiré shape, spreading from bottom to top to the upper leaf sheath. The sheath of the disease is yellowish due to damage to the tissue. When dry, the center of the lesion is grayish white or grass green, and the edge is dark brown. When it is wet, there are many white spider filamentous myceliums ...
