To control borers, remember a point in time, and it's OK

Farmers who grow rice know about the heartworm. Its harm to rice is relatively large, especially the three borers.

The three borers feed on rice with larvae, and form dry heart seedlings in the stems of moths at the seedling stage and tillering stage, or moth into the leaf sheath, so that yellow-brown stripes appear at the victim site, forming a "dead sheath". For example, during the gestational panicle stage, the stem is formed, and a dead panicle is formed. After the ear is extracted, the moth stem is formed, and the "white panicle" is formed when the ear stem is damaged, which damages the yield and even fails to harvest in severe cases.

So, when exactly will it take to control borers? Most farmers don't know much about it. When I saw someone in my neighbor's back sprayer, I hurriedly asked what medicine to take, or simply put on a cage with the chicken, and I also medicated others. However, I don't know that the respective situations are different, some are seedling transplanting, and some are direct rice. And the time for each household to plant seedlings and broadcast live has a first and another. It is precisely because of these actual situations that the time for the control of borers cannot be a uniform time.

Now tell you a simple method for thousands of households to control borers. Just remember the time of planting and direct broadcasting, and it is 0K.

Seedling fields: control borers 20 to 25 days after planting.

Live field: Control borers 45 to 50 days after live broadcasting.

The second control time is 20 days away from the first.

When there is sporadic spikes, the medicine is given again.

For example, before August 15, there is no need to spray anti-borers. At this time, the harm of borers is relatively small.
