It's better to spray for the first time. When the temperature is high and the evaporation in the field is high, it should be used before 10 in the morning and after 4 pm, which can not only reduce the dosage of chemical liquid, but also increase the dosage of chemical liquid and the permeability of crops, which is beneficial to improve the control effect. When there are 30 new insect bracts in 100 cluster of rice, the curly leaves are about an inch long, and the curly bracts are still green.

Secondly, the comprehensive control effect is better than the commonly used 5% fipronil 40ml/ mu and 20% triazophos 140ml. Because pesticides have strong permeability, they can enter the xylem through the stem epidermal cell layer, and thus spread to other parts along the xylem without use. In order to master the correct dosage, use 20% Kangkun 10ml per mu, add 50kg of water, and spray rice evenly after 4 pm.

The third point is that it is only suitable for the first time after seedling field or transplanting. Not suitable for future use. In order to avoid drug resistance, crops or pests should be used 2-3 times in a season, with an interval of more than 15 days. Different dosage forms, contents and suitable crops. Users should choose different pesticide contents and dosage forms according to different crops.

The dosage form and content have been registered for controlling main rice pests.
