Climate Change’s Impacts on Weeds and Herbicide Efficacy: A Review

ISSN: 2319-7706 Volume 6 Number 9 (2017) pp. 2846-2853 Journal homepage: http://www.ijcmas.com Climate change is a natural and continuous process. But recent relatively rapid change in climate occurs due to anthropogenic activities which makes alarming attention because it contributes largely to global warming by affecting the greenhouse gases (GHGs) and aerosols. GHGs mainly CO2, methane, nitr...

PEST MANAGEMENT: WEEDS Urea Ammonium Nitrate Effects on Bispyribac and Penoxsulam Efficacy

Greenhouse studies were conducted in 2006 to evaluate the effects of urea ammonium nitrate (UAN) solution on bispyribac and penoxsulam efficacy on barnyardgrass and hemp sesbania. Bispyribac and penoxsulam treatments containing an adjuvant and UAN significantly reduced barnyardgrass biomass over most treatments without UAN. Urea ammonium nitrate did not increase hemp sesbania biomass reduction,...

Herbicide Metabolism in Weeds — Selectivity and Herbicide Resistance

The metabolic detoxication/bioactivation pathways, the levels and activity of enzymes, and endogenous cofactors mediating these reactions in crops have been well document‐ ed; however, much less evidence has been accumulated in weed species. The herbicide metabolism as a selectivity factor is summarized with special attention to acetyl-CoA car‐ boxylases (ACCase)-inhibiting aryloxyphenoxypropio...

Herbicide Resistant Weeds and Crops

Modern herbicidal weed control often exploits physiological differences among plants and takes advantage of herbicide tolerance or resistance in crop plants to bring about the selective removal of susceptible weeds. The Weed Science Society of America defines herbicide tolerance as “the inherent ability of a plant to survive and reproduce after herbicide treatment” which suggests that herbicide...
