Sowing in the mosquito net

To deal with yellow dwarf diseases and twisted leaves dwarf diseases on rice due to spread of brown plant hopper, winter-spring crop 2006-2007 seed rice farms as well as farmers producing seed rice in An Giang province mostly " sow plated in mosquito nets ". When I first thought about playing, this was a very scientific solution, significantly reducing the brown backed rice plant hopper disease in the plating stage. Because scientists have also studied to show that if the rice is infected at a smaller stage, the higher the rate of stunted, twisted leaves dwarf disease, but if more than 25 days of rice is newly infected, the damage will be less. go.

The solution "sowing in the mosquito net" is considered very feasible for the following reasons:

• The area of ​​sowing is small, only 100-120m ^{2 of} plating can be planted for 1 ha of paddy fields, so it costs less to buy nets.
• Sowing in 12-15 days of sowing and transplanting (even 20 days) brown planthopper will not have the condition to spread the disease so it is unlikely that rice will become infected in the period of 15-20 days.

How to do the following:

(Photo: Gpagri) The substrate material for sowing is similar to the way of making pitches (cocopeat, pond bottom, banana peel, or small chopped coconut, smooth plastic sheet). Seed rice is normally soaked but to help the rice to be healthy, against brown backed rice plant hoppers and other sucking insects, before sowing seedlings, it is about 6-12 hours to process seeds with Cruiser Plus with a dose of 30cc for 100kg of rice seed will protect rice from 7-10 days after sowing. Actara sprayed 1 day with 4g / 16 liter bottle of sprayed rice before spraying. If plated over 15 days, it is recommended to cover with a thicker layer of sowing material (1.5-2cm) and to sow slightly less (120-150m2 of plating for 1 ha of cultivated field) to help with adequate nutrient plating and distribution. grow better.

Using the nets to dry rice, small holes for mosquito nets, 25-30cm from the ground, make sure not to let hoppers from outside. It can be plated in the mosquito net until the date of plating and transplanting because it is a net, so light, irrigation water, spraying and foliar fertilizer . all pass through well. But if sowing where there are many shade trees, it should be unloaded, 2-3 days / time so that the plating does not reach high and the photosynthesis rice is better. The solution of " sowing seedlings in the mosquito net " is only to deal with the situation of outbreaks of yellow dwarf diseases and twisted leaves dwarf diseases spread by the brown plant hoppers that are difficult to control today, when the epidemic is no longer necessary, it is not necessary to sowing seedlings in the mosquito net because it costs more and more effort anyway.
