| ABSTRACT: Increased use of glyphosate in transgenic soybean areas has selected resistant and tolerant weed species. The aim of this study was to evaluate chemical management strategies for controlling Borreria latifolia and Richardia brasiliensis at pre-emergence (Pre), early post-emergence (Poste) and late post-emergence (Postl). Six experiments were carried out in a completely randomized design with four replicates per treatment in the Pre experiments and three in the Poste and Postl experiments, for each of the species. In the Pre experiments, tests were performed with herbicides imazethapyr, sulfentrazone, chlorimuron, diclosulam, S-metolachlor and saflufenacil. In the Poste experiments, seedlings were sprayed with herbicides bentazon, fomesafen,... |

| ABSTRACT The control of morning glory (Ipomoea spp. and Merremia aegyptia) was evaluated in five commercial sugarcane-production fields receiving applications of the herbicides sulfentrazone (0.9 kg ha-1), amicarbazone (1.4 kg ha-1), imazapic (0.147 kg ha-1), and hexazinone + tebuthiuron (0.325 + 0.75 kg ha-1) applied pre-emergence in either the dry season (July and August) or in the semi-wet season (early October); mesotrione alone (0.192 kg ha-1) or in combination (0.12 kg ha-1) with atrazine (1.5 kg ha-1) or diuron + hexazinone (0.491 + 0.139 kg ha-1) applied post-emergence in the wet season (November), and the phytointoxication of the chemical treatments for sugarcane. Five species of morning glory (Ipomoea hederifolia, Ipomoea nil, Ipomoea quamoclit,... |

| Experiment on pre-emergence and post-emergence herbicide application for weed control in farmer's field conducted in Ban Yangrak, Khokcharoen district, Lopburi province, during August-November 2008. The experiment laid out in RCB, composed of 10 treatments, with 3 replications. The objective of this experiment was to study on the efficiency of herbicides and their effect on field corn, KSX 4901 variety. The results revealed that weed found in the experiment were purple nutsedge (Cyperus rotundus), wild poinsettia (Euphorbia heterophylla), horse purslane (Portulaca oleracea), tropical spiderwort (Commelina benghalensis), running grass (Brachiaria reptans), and jungle rice (Echinichloa colona). The application of 2,4-D, glufosinate, fluroxypyr and paraquat... |
