Ms. Nguyen Thi Le, Deputy Director of An Giang Plantation – Plant Protection Department said: In the 2021 autumn-winter rice crop, An Giang recommends the sowing time frame starting from July 15 to September 10. In the autumn-winter crop, sowing often falls in the weather with a lot of rain and floods, so it is difficult to produce. Besides, there are often some pests and diseases such as brown planthopper, rice blast disease, leaf blight disease, seed smudging disease.

In order for this rice crop to be successful, the agricultural sector should focus on recommending localities to apply scientific and technical measures such as “3 decrease, 3 increase” and “1 must 5 decrease”; apply the method of sowing sparsely with the recommended amount of seed from 80-100 kg/ha.

In particular, focusing on implementing water-saving solutions, promoting the application of ecological technology. Planting flowers on the edge of the field to attract beneficial natural enemies to minimize the use of pesticides in the first 40 days after sowing.

Strengthen propaganda and guide farmers to use pesticides according to the “4 right” principle, giving priority to using biological and organic fertilizers. It is recommended that farmers strengthen measures to help rice plants stay healthy such as micronutrient supplements, fertilizers containing calcium, silicon, etc. to help rice plants increase their natural resistance, in order to reduce costs and increase profits at the end of the crop.

Regarding the structure of rice varieties, Ms. Le added, autumn-winter rice is considered the third main rice crop of the year, so for many years, An Giang’s agricultural industry has always followed the direction of the Ministry of Agriculture and Rural Development and encouraged Report localities in the province to use high quality rice varieties for production.
