In the late stage of early rice growth, it was mostly in the rainy season, the humidity in the field was large, and the permeability was poor. The various diseases mainly caused by sheath blight were heavier. Here, the majority of farmers are reminded to pay attention to the timely use of drugs.
If the early rice sheath blight is controlled once, it should be late, and it is generally appropriate to use the drug after early rice. The main purpose is to control the vertical rise of the disease to ensure that the three functional leaves after the early rice are not harmed. There are two options for the selection of the drug. One is to spray 30% of the seedlings (phenylene bromide) per acre, and spray evenly 25 to 30 kilograms of water. It can not only control the sheath blight, but also treat various fungi in the early rice stage. Disease. The other is a conventional pharmacy, which can be sprayed with 3%% sulphur (pyrimidine nucleoside, jinggangmycin) 120-200 g per mu or 100% rice borax (poly carbazole) 100 g to 25-30 kg of water. .
In recent years, bacterial diseases of rice have risen. In some areas, bacterial blight of rice has occurred in the early rice stage. The prevention and control of bacterial blight must be caught early. When the disease occurs in the field, it should be used in time. It can be used 2% per acre. 100 ml of rice-removing solution or 250 g of 20% leaf cumazole spray evenly on water 25~30 kg.
The early rice pests are mainly rice locusts, some of the areas of the gray planthoppers and the rice weevil, and the control of rice scorpion horses and gray planthoppers can use Jin Haonian, Aktai and other medicinal agents, and the control of rice stalks can be used by Shennongbao and Galen. These agents are important for the prevention of some diseases. In the epidemic areas of bacterial blight and bacterial stripe disease, it is necessary to catch a season of rice seedlings at the 3rd leaf stage and 5~7 days before transplanting to spray 2% of the rice liquid. 100 ml of the agent can effectively delay and alleviate the incidence of the field; the stripe leaf blight epidemic area must prevent and control the gray planthoppers in the field, and prevent the seedlings from getting sick.
