“…The following year, these treatments controlled common lambsquarters 75 and 92%, respectively. Vencill et al (1990) reported variability in common lambsquarters control with imazethapyr and attributed this difference to variations in rainfall after application. However, in our studies, at least 2.3 cm of rainfall was recorded within 1 WAT in both years.…”

Field studies were conducted in 1999, 2000, and 2001 to evaluate mesotrione at 105 and 210 g ai/ha alone and in mixtures with imazethapyr at 70 g ai/ha and the prepackage mixture of imazethapyr at 47 g/ha plus imazapyr at 16 g ai/ha postemergence. Mixtures of mesotrione with imazethapyr and imazethapyr plus imazapyr controlled common ragweed, common lambsquarters, and morningglory species better than imazethapyr or imazethapyr plus imazapyr alone. Similarly, mixtures of mesotrione with these imidazolinone herbicides improved the control of giant foxtail over that by mesotrione alone. Crop injury did not exceed 11% with all treatments and appeared as transient stunting. Yields of corn treated with mixtures of mesotrione plus imidazolinone herbicides were highest in 2000 and 2001, when rainfall was higher than in 1999.

“…In southern Ontario, vegetable crops are commonly grown in rotation with agronomic crops such as field corn, as they offer growers greater value than traditional agronomic crops. Vegetable crops differ in their response to residues from herbicides applied in previous years (Greenland, 2003;O'Sullivan et al, 1998O'Sullivan et al, , 1999Vencill et al, 1990).…”

There is little information published on the effect of residues from postemergence (POST) applications of foramsulfuron and preemergence (PRE) applications of isoxaflutole, and isoxaflutole plus atrazine in the year after application on vegetable crops. Three trials were established from 2000 to 2002 in Ontario to determine the effects of residues of foramsulfuron, isoxaflutole, and isoxaflutole plus atrazine on cabbage, processing pea, potato, sugar beet, and tomato 1 year after application. Aside from a reduction in sugar beet plant stand, there were no visual injury symptoms in any crop at 7, 14, and 28 days after emergence (DAE) in any of the herbicide carryover treatments. Isoxaflutole residues reduced shoot dry weight and yield as much as 27% and 28% in cabbage, and 57% and 60% in sugar beets, respectively. The addition of atrazine to isoxaflutole caused further reductions in shoot dry weight and yield of cabbage and sugar beet. Isoxaflutole plus atrazine residues reduced shoot dry weight and yield as much as 42% and 43% in cabbage, and 58% and 82% in sugar beets, respectively. There were no adverse effects on shoot dry weight and yield of processing pea, potato, and tomato from isoxaflutole or isoxaflutole plus atrazine residues in the year following application. Foramsulfuron residues at either rate did not reduce shoot dry weight or yield of any crops 1 year after application. Based on these results, it is recommended that cabbage and sugar beet not be grown in the year following the PRE application of isoxaflutole or isoxaflutole plus atrazine.

“…Studies indicate that for the most part, tolerance of beans to s-metolachlor and imazethapyr is influenced by rate, cultivar and environmental conditions (Vencill et al 1990;Wilson and Miller 1991;Newsom and Shaw 1992;Renner and Powell 1992;Arnold et al 1993;Bauer et al 1995;Osborne et al 1995;Ward and Weaver 1996;VanGessel et al 2000).…”

Soltani, N., Shropshire, C., Cowan, T. and Sikkema, P. 2003. Tolerance of cranberry beans (Phaseolus vulgaris) to soil applications of s-metolachlor and imazethapyr. Can. J. Plant Sci. 83: 645-648. There is little information on the tolerance of cranberry beans to preplant incorporated (PPI) and preemergence (PRE) applications of s-metolachlor and imazethapyr, either alone or in tank mix combination, for selective weed control in cranberry beans in Ontario. Tolerance of two cranberry bean cultivars, Hooter and SVM Taylor, to PPI and PRE applications of s-metolachlor, imazethapyr and their tank mix combination at the label rate (1×) and twice the label rate (2×) were studied at two Ontario locations (Exeter and Ridgetown) in 2001 and 2002. There were no differences between the two cultivars in their responses to the herbicide treatments. PPI and PRE applications of s-metolachlor alone at the 1× and 2× rate had no effect on visual crop injury and no negative effect on plant height, dry weight and yield compared to the control. The PPI and PRE applications of imazethapyr at the 1× rate did not result in significant visual crop injury, and had no negative effect on bean height and dry weight, but at the 2× rate there was significant visual crop injury, a decrease in height with the PPI application and decreased dry weight with PPI and PRE applications. No negative effect on cranberry bean yield was observed with the application of imazethapyr at either the 1× or 2× rates. The PPI and PRE applications of the tank mix of s-metolachlor plus imazethapyr at the 1× rate did not result in significant visual crop injury or decreases in bean plant height or dry weight. At the 2× rate, there was significant visual crop injury, a decrease in bean plant height with PPI and PRE applications and decreased dry weight with the PPI application. The tank mix of s-metolachlor plus imazethapyr at the 1× rate had no effect on yield, but the PPI application at the 2× rate caused a decrease in yield at 1 of the 4 site-years. Les deux cultivars ont réagi de la même manière aux traitements. L'usage PPI et PRE du s-méto-lachlor aux deux taux d'application n'entraîne pas de dommages visibles à la culture et n'a aucune incidence négative sur la hauteur des plants, le poids sec ni le rendement, comparativement aux témoins. L'usage PPI et PRE d'imazéthapyr au taux 1× n'entraîne pas non plus de dommages visibles importants à la culture et n'a pas d'incidence négative sur la hauteur des plants ni sur le poids sec, mais au double du taux normal, on note d'importants dommages à la culture, les plants sont plus petits avec le traitement PPI et il y a réduction du poids sec avec les traitements PPI et PRE. Le rendement du haricot canneberge n'est affecté par l'imazéthapyr à aucun des deux taux d'application. L'usage PPI et PRE du mélange n'entraîne pas de dommages visibles importants ni de forte diminution de la hauteur des plants et du poids sec au taux d'application normal, mais au double de ce taux, on note des dommages visibles sensibles, une rédu...
