On the morning of May 2, the Department of Agriculture and Rural Development inspected and evaluated the effectiveness of the spraying campaign to prevent and control leaf rollers and some other pests.

Leaders of the Department of Agriculture and Rural Development check the density of pests and diseases on spring rice in Vu Thang commune (Kien Xuong).

The campaign to spray pesticides to prevent and control leaf rollers and other pests took place from April 29 to May 3. According to the agricultural sector's synthesis, by May 2, localities had basically completed spraying. The pesticides were of guaranteed quality, quantity and type. Farmers concentrated on spraying pesticides on April 30 and May 1, ensuring compliance with the province's techniques and instructions.

However, due to the very high density of leaf rollers in the spring crop, through inspection at the field of Vu Thang commune (Kien Xuong), after 3 days of spraying, the density of small leaf rollers was from 15 - 30 individuals/m ² , eggs were 100/m ² ; the sprayed area did not meet technical standards, the density of worms was from 200 - 400 individuals/m ² ; in some areas that had not been sprayed, the density of worms was from 800 - 1,000 individuals/m ² .

Officers of the Department of Crop Production and Plant Protection check the density of small leaf rollers in Vu Thang commune (Kien Xuong).

The small leaf roller is forecast to arise on a large scale, with the risk of crop failure. The agricultural sector requires localities to strengthen propaganda and mobilize people to spray pesticides 3-5 days after the first spraying to spray pesticides for the second time to kill small leaf rollers in rice areas with a density of 20 insects/m ² or more; combine prevention and control of planthoppers in areas with a density of 1,000 insects/m ² or more.
