“…La bentazone participe en revanche à plusieurs mélanges homologués. Outre les mélanges cités plus haut, elle peut être associée à l'atrazine, au bromoxynil pour le désherbage du maïs (Gerwick, 1988) (Rao et Harger, 1981), ou à des insecticides tels que le malathion, le parathion ou le diazinon (Campbell et Penner, 1982 ;Blumhorst et Kapusta, 1987 (Hammann, 1995 (Gerwick, 1988 ;Wanamarta et al, 1989 ;Aguero-Alvarado et al, 1991 ;Grichar, 1991). Le mécanisme de l'antagonisme n'est pas expliqué dans sa totalité.…”

herbicide / aclonifen / bentazone / synergie / gaillet Summary — Joint action of aclonifen and bentazone applied with or without formulation. Bioassays were carried out with cleavers plants treated with aclonifen and bentazone, in controlled conditions. The active ingredients were applied alone, as a mixture, dissolved in acetone/water, or as their commercial formulations (Challenge 600 and Basagran). The efficacy of mixtures was evaluated with 2 methods. One used a factorial design and calculated an additivity of effects. The other worked from response curves and was able to calculate an additivity of effects or an additivity of doses. When aclonifen and bentazone were mixed in a ratio of 1.25, an antagonism was detected at low doses and a synergism at high doses. The formulated products, mixed in the same ratio, gave the same types of effects. However, the synergism of the formulated products was stronger than that of the active ingredients and focused on the high doses inducing the death of plants. Thus, the efficacy of the formulated products would add the synergistic effect of active ingredients and a crossed effect of formulation agents.

Field studies were conducted in 1987 and 1988 to evaluate the control and competitiveness of common lambsquarters in soybeans when present at four densities and when removed at four time intervals. Common lambsquarters were removed by hand or treated with a postemergence herbicide application of bentazon plus acifluorfen. Common lambsquarters could remain 10 weeks following soybean emergence before a 20% soybean yield reduction occurred when weeds were removed by hand. When treatment was attempted with postemergence herbicides, a 20% yield reduction occurred in 1987 if application was not made prior to 5 weeks after emergence. In 1988, all postemergence herbicide applications failed to control lambsquarters due to drought conditions. The postemergence herbicide's degree of control was reflected in the number of remaining lambsquarters plants. Common lambsquarters seed production and germination was not influenced by postemergence herbicide application. There was a strong correlation between dry weight of uncontrolled common lambsquarters plants and seed produced per plant.
