Plants with rhizomes and plants without rhizomes
Must plants are without rhizomes and in generally they are must easy to control with glyphosate when they are small, but it is also possible to control them when they are larger. Plants with rhizomes need to be large before it is possible to get glyphosate transported into the rhizomes and control the rhizomes. If sprayed to early only the top of the plants are controlled.
In order to obtain desired effect at an optimal dose, is very important the growing stage, how large are the leaves and weeds capacity of absorption and transport when we apply the herbicide.
Controlling plants without rhizomes
For plants without rhizomes the best herbicide effect at an economical dose is when the weed’s growing stage is at the beginning, small plants. The main part of glyphosate is taken up by the plant within 10 hours. The glyphosate is inside the plants. 12 hours after spraying full effect is reached and the soil can be tillage and a new crop planted.
