Controle de plantas daninhas com diuron em diferentes condições de luz
| Resumo: | This study aimed to evaluate the weed control with the herbicide diuron sprayed in pre- and post-emergence, either under shade or full sun. It was studied the effect of the diuron at in the formulation 500 SC at 3.2 and 4.8 L ha-1 of the trade product on the plants of Euphorbia heterophylla, Ipomoea grandifolia and Raphanus raphanistrum sprayed in pre-emergence, as well as the same doses sprayed in post-emergence on plants of E. heterophylla, I. grandifolia and Senna occidentalis. For both application times, a set of pots was planted and maintained either under full sun or under a mesh that allowed only 30% of the radiation to reach the pots. The control levels were considered excellent for both application times; however there was a slower control of plants subjected to shading independent of the dose applied. |
