Última Weed Management in Rice under Sprinkler and Flood Irrigation Systems Planta Daninha HELGUEIRA,D.B.; D’AVILA ROSA,T.; GALON,L.; MOURA,D.S.; MARTINI,A.T.; PINTO,J.J.O.. ABSTRACT: This study aimed to assess the efficiency and selectivity of herbicides in rice submitted to sprinkler and flood irrigation systems. The experimental design was a randomized block design arranged in a 2 × 9 factorial scheme. Factor A consisted of irrigation systems (sprinkler and flood) and Factor B consisted of herbicide treatments (T1 - control; T2 - imazethapyr + imazapic, 75 + 25 g a.i. ha-1; T3 - imazethapyr + imazapic, 150 + 50 g a.i. ha-1; T4 - imazapic + imazapyr, 73.5 + 24.5 g a.i. ha-1; T5 - imazapic + imazapyr, 147 + 49 g a.i. ha-1; T6 - imazethapyr, 106 g a.i. ha-1; T7 - imazethapyr, 212 g a.i. ha-1; T8 - sequential application of imazethapyr + imazapic, 75 + 25 g a.i. ha-1; and T9 - sequential application of imazapic + imazapyr, 73.5...

ABSTRACT: The use of dietholate seed treatment, as well as the use of preemergence clomazone, can affect the selectivity of the imidazolinones chemical group of postemergence herbicides applied in crops Clearfield™. The aim was to evaluate the morphophysiological effects of a formulated mixture of imazapyr + imazapic applied in postemergence in combination with seed treatment with dietholate and applying in preemergence of clomazone on Avaxi CL rice hybrid cultivar. The experiment was conducted in the agricultural year 2012/13, in a greenhouse. The experimental design was completely randomized in a factorial design with four replications, in which factor A consisted of seed treatment with dietholate and applied clomazone herbicide in preemergence on rice...

ABSTRACT: Herbicides of the imidazolinone group have been used in irrigated rice and presented a long persistence in the soil, especially in floodplain areas with a low drainage, and could cause environmental contamination. This study aims to evaluate the leaching and residual of herbicides belonging to the imidazolinone group in sprinkler and flood irrigation systems. The experiment was carried out under greenhouse conditions, with the application of the herbicides imazethapyr, imazethapyr + imazapic, and imazapyr + imazapic in soil irrigated by flooding and sprinkling. Subsequently, the soil was collected from the layers of 0-5, 5-10, 10-15, 15-20, and 20-25 cm and packed in 500 mL capacity plastic pots in order to sow tomato as a bioindicator plant of...
