01. Big weeds, not small weeds
It means waiting until the weeds have grown to a certain period before starting to use the herbicide. If the weeds are used when they are small, the area of the weeds in contact with the solution becomes smaller, which is not conducive to the death of the weeds and the most obvious situation is a rebound or poor results. However, weeds should not be too large, if they are too large, resistance increases and the dosage needs to be increased. In general, weeds are best applied when they are in the 2-4 leaf stage.
02. Dense but not thin
What does this phrase mean again? Don’t start applying a dose just because a small amount of weeds have just grown in the ground. The result of this is that after a month and a half or so, you will find more and more weeds in the ground than before the dosing. If the weeds are too thin, most of the solution hits the ground and then evaporates, and after a few days, the weeds slowly grow out, which means that the previous days’ application has no effect at all and you have to do it all over again. So, wait until the weeds are almost out and a little denser before you hit the ground.
03. Wet not dry
What is the meaning of this last sentence? In fact, it depends on the moisture level in the ground. If the moisture level in the ground is not good and the weather is dry, try not to dose. Why? If the ground is dry, the weeds are dehydrated and their pores are closed in order to retain moisture. So some people say, the weeds are already 2~4 leaves, and they are still dense, if there is a drought at this time, if I don’t apply the medicine, won’t I miss the best time? This problem is often encountered in actual production, there are 2 ways to solve it, one irrigation and watering, the second in the dosing more water, increase the amount of water used, but the overall concentration of the solution can not be reduced.
