1 Corresponding author: [email protected]; 352-392-9981 ABSTRACT: There are several alternative herbicides with different modes of action for control of invasive plants in natural areas. Of the four classes of herbicides commonly used on invasive plants in natural areas of Florida, the acetolactate synthase (ALS) inhibitors, imazapyr, imazapic, and metsulfuron methyl, are the most likely...

Ryegrass and turnip are weeds that cause high yield losses when infesting barley, thus requiring adequate management. In this context, the aim of study was to evaluate selectivity different herbicide treatments weed control in barley crop, cultivar BRS Cauê. Two field experiments were conducted randomized blocks, with four replications. The used were: pendimethalin (800 g·ha-1), sulfentrazone +...

Wheat, a significant grain crop, is the second-largest crop in terms of acreage and output after rice. It farmed on around 217 million hectares worldwide, with nearly half it poor nations. Wheat member Poaceae family. Weed flora wheat includes Phalaris minor, Avena ludoviciana, Chenopodium album, Lathyrus aphaca, Vicia sativa, hirsute, Medicago hispida, Cichorium intybus, Asphodelus tenuifolius...

Orange hawkweed is a perennial European plant that has colonized roadsides and grasslands in south-central and southeast Alaska. This plant is forming near-monotypic stands, reducing plant diversity, and decreasing pasture productivity. A replicated greenhouse study was conducted in 2006 and repeated in 2007 to determine the efficacy of six herbicides (aminopyralid, clopyralid, picloram, piclor...

A laboratory study was conducted to investigate the mineralization of metsulfuron-methyl (MSM) in paddy soils in response to soil moisture, temperature and soil properties. The results indicated that MSM mineralization was relatively limited in the paddy soils when soil temperature was low. Only 2.2-6.0% of the applied (14)C mineralized after 84d of incubation at 15 degrees C. The mineralizatio...

Hollow graphitic carbon nitride (HCN) ZrO2/g-C3N4 hybrid composites (HCN–ZR) and the target catalyst Fe/ZrO2/g-C3N4 (HCN–FZR) were prepared successfully by a solvo-thermal method and evaluated for photo-degradation of organic pollutants, i.e. MO, and herbicides, metsulfuron methyl (MTSM). These materials were characterized by a variety of techniques, including Fourier transform infrared spectro...
