Abstract/Contents:Common lambsquarters (Chenopodium album L.) is one of the most important weeds in corn and soybean. Laboratory and greenhouse studies were conducted to measure the contact angle and spread area of primisulfuron droplets with and without surfactants and to examine the effect of two surfactants on primisulfuron activity in controlling common lambsquarters. Primisulfuron rates were used as 2X, 1.5X, 1X, and 0.5X, where 1X represented the recommended use rate (40 g ai ha-1). Induce (non-ionic surfactant) and Silwet L-77 (organosilicone surfactant) was used at 0.25 and 0.10% (v/v), respectively. The contact angles of the 1-μl droplets of primisulfuron (with and without surfactants) were measured on the adaxial leaf surface of common "Diclofop-resistant Italian ryegrass (Lolium multiflorum L.) has become a common and troublesome weed in winter wheat (Triticum aestivum L.). Until recently, diclofop was the only herbicide registered for consisten control of Italian ryegrass. Mesosulfrom-methyl, which has excellent activity on Italian ryegrass, was available for use in the 2003 to 2004 growing season in winter wheat. With the commercial relase of mesosulfuron, diclofop-resistant ryegrass can now be effectively controlled in wheat. In the 2003 to 2004 growing season, field studies were conducted to evaluate the utility of mesosulfron to manage Italian ryegrass in winter wheat. Mesosulfuron was applied at 0.0134 lb ai/A and was mixed with methylated see oil (MSO) at 1.5 pt/A (0.75% v/v) and urea ammonium nitrogen (UAN) at 4.0 pt/A (2.0% v/v). Mesosulfron treatments were applied postmergence (POST) either alone or in combinations or sequences with other herbicides. These studies were conducted in a randomized block design with four replicates. Visual control ratings and spike density of Italian ryegrass were collected just prior to wheat harvest, and wheat yields were collected using a small-plot combine. An additional study was conducted under weed-free conditions to evaluate cultivar tolerance to mesosulfuron. In this study nine different wheat cultivars were planted in a split plot design and treated POST with no mesosulfuron or mesosulfuron at either at 0.0134 lb ai/A or 0.0268 lb ai/A. Visual crop injury ratings and wheat yeild were collected for the cultivar-tolerance study. All treatments were applied usuing a tractor-mounted sprayer with an application volume of 25.0 gpa. All mesosulfuron treatments controlled 2-leaf Italian ryegrass >97% and treated-wheat produced minimum yields of 102 bu/A; untreated checks produced 42 bu/A. Delaying the applications of mesosulfuron to mid-March or early April resulted in reduced Italian ryegrass control. Though yeilds were ow from these delayed applications, wheat lodging was eliminated and foreign matter content of harvested grain was greatly reduced when compared to the untreated checks. In conclusion, mesosulfuron controlled Italian ryegrass and wheat yields were significantly increased. All cultivars evaluated for mesosulfuron tolerance demonstrated excellent tolerance to this herbicide."
