How are weed seeds transmitted?
The seeds of grasses and the seed base of most plants survive in the harshest climatic Iranian Pistachio conditions and retain their vigor, which is why you see in the deserts that have not rained for years, with a good rain in the season In the spring, many grasses turn green, and the seeds move in different ways:

Practical weed control solutions
The beginning of spring weeds are very thin and vulnerable. Perhaps the best time to fight weeds can be considered April 15, with a simple reaper, or tiller or even a simple paving can bring more oxygen to the roots of trees and Easily remove newly germinated seeds.
Chemical control is very important in the stage of seed production in weeds. It should be noted that weeds are weak in the early stages of their growth period and have little power to absorb water and nutrients and compete with pistachios, but over time they become very dangerous and harmful during the early stages of growth and maturity. . Chemical and mechanical control of weeds in the early stages of growth is much easier and more successful than during the maturation of weeds.
Of course, it should be noted that some weeds that have been in your soil for years are propagated by roots. In the case of permanent weeds such as chicken, it is better to fight with a combination of mechanical and chemical, and of course it should be noted That to eradicate permanent and dangerous weeds must be patient and can not be achieved in one year. If you use high doses of herbicides, you will also damage your pistachio trees.
