How to apply various types of weed killers?

The weed-killing pesticides are mainly known as Herbicides. With Herbicides’ help, you can get an almost weed-free lawn and can increase the productivity of vegetables and fruits significantly.

What time is best for using weed killers?

Spring is the best time for using weed killers. It would be better to use weed killer before a few weeks of cultivating the trees in your lawns.

  •     Processing of actively overgrown weeds;
  •     Proper temperature;

Apply the solution of 0.2-0.4% ammonium nitrate before several days of the treatment with herbicides. Otherwise, spread 0.02 – 0.03 pounds nitrogen-based fertilizer per 10 square feet on the lawns after the irrigation and one week previous to the application.

Suppose you do not get a promise from the weather forecasters about suitable weather after applying herbicides and don’t have enough time to delay the treatments. In that case, you add adhesives with your pesticide mixture to get the expected result.

Perhaps, using adhesives is the only way to decrease the herbicide dose without reducing their effectiveness. But those adhesives should have a biological origin and Liposam is an example of it. If you use it with selective herbicides, it will prevent chemicals from spreading to the cultivated plants and soil.
