Winter-spring paddy production 2011 - 2012 is very close, along with other preparatory work, the handling of prevent seed black stripe dwarf is essential. Because this is one of the pests objects appear in the field caused by a virus, insects infect is white back aphids. Evolution of complex diseases. There is no cure the disease caused because vius mainly insect-transmitted disease prevention.

In fact, in 2010 black stripe dwarf disease appears scattered throughout the locality, with a total area of ​​7.5 ha of the winter-spring rice and crops. Winter-spring rice crop in 2011 has 1.4 ha of rice affected. Although rice infected area is not much and did not affect yield, but the field shows that the province has been the source of this dangerous disease. Mr. Bach Van Huy, Department Head Department of Plant Protection of province, said: To be effective against aphids and white back, the best measures is of special drugs to treat seeds prior to soaking sowing. This measure also kills thrips, help seeds sprout shark, root growth and nutrient absorption maximum right from the galvanized young. Thereby, increasing resistance of coated and rice that are implanted into the unfavorable conditions of weather, especially having cold weather lasting harm. Provincial Plant Protection Department has recommended to the people full of drugs used to treat seeds, including drugs and Cruier 312.5 Enaldo 40FS.

It is known that to prevent black stripe dwarf disease on rice, while preparing to enter the new production, Provincial Plant Protection Department was promoting, guiding people to the technical measures, including the handling of seeds before when soaked. However, the proportion of seed is processed in the province of the very low. Typically, winter-spring crop 2010 - 2011 the province has only 9.5% of the rice seed is processed. In particular, Binh Luc district has less than 1% of the rice seed is processed, Thanh Liem district 4.7%, other areas reached from 8 to 18.7%. The main cause of this situation is because the subjective thoughts of a big section of local officials and residents, because of the appearance of black stripes dwarf disease has not spread into an epidemic in the field, so the extent of damage productivity is not clear. Therefore, although the cost of seed treatment only from 2 to 3 trillion dong / sao, but people are still not done. Mr. Nguyen Thanh Cong, Chairman of the Cooperative Agricultural Service An Do (Binh Luc) said: At the beginning of each service, cooperative management had fully implemented the content of the preparations for the season new and more focused on the handling of seed black stripe dwarf prevent. Specifically, Winter-Spring 2010 - 2011, along with the propaganda and mobilization of staff cooperative had taken the lead in special drugs to treat pests other than seeds, but people still do not respect sewing room effectiveness of this disease.

First of severity and risk of short black streaks may appear, on a large scale outbreak in the winter-spring crop 2011 - 2012, Provincial Plant Protection Department has implemented measures specific to the facility. Accordingly, the field sanitation kill pathogens, in particular, measures to treat the seeds with special medications should be respected. Through the operation of the plant protection staff establishment propaganda and guide farmers to dispose of 100% of the seeds before soaking. According to Mr. Bach Van Huy, rule generation, development of striped dwarf disease in rice has not been determined. So, Winter-Spring 2012 production, black stripe dwarf disease is still the main object must be very interested in prevention and early cases. Most important is the prevention of back and white aphids from seed before sowing. This is one of the preparation to help ensure successful crop.
