Möglichkeiten der chemischen Unkrautbekämpfung in Luzerneim Iran

Summary

For the purpose of weed control in Alfalfa, testplots on the basis of randomized block design have been installed by the Aoricultural Faculty of Teheran University. 4 different Herbicides have been applied in 8 treatments. The significant results of these tests have shown that Sinbar, at an application of 640 g. A. i. per ha, was the most effective Herbicide. The plots treated with Sinbar produced the lowest weight of weeds and the highest weight of Alfalfa.

Kloben and T. C. A., in separate, and also mixed application, were second, and a mixture of Afalon and T. C. A. were third.

At the end of this report, the qualities of Sinbar are mentioned. The tests have shown that many Mono- and Dicothyledon-weeds exist in Alfalfa fields during spring, while in autumn the Monocothyledones increase.

The common opinion that the growth of Alfalfa plants will suffocate the weeds, cannot be confirmed by us. Weed control in Alfalfa by Herbicides, which are tested and recommended, is economically profitable.
