Maleic hydrazide (1, 2-dihydropyridazine-3, 6dione) is an organic plant growth regulator which has found use in such varied areas as prevention of sucker formation in tobacco, prevention of sprouting of some stored vegetables, and as a herbicide. In commercial application the diethanolamine salt (diethanolammonium maleic hydrazide or diethanolammonium-1 ,2-dihydropyridazine-3, 6-dione) is often...

abstract extensive application of atrazine and its toxicity in environmental has attracted researcher attention for finding new degradation methods to this organic pollutant. biodegradation is one of most effective methods for removing atrazine. due to the importance of atrazine herbicide as an organic pollutant, a design carried out at factorial experiment in completely randomized design with ...

A user-friendly computerized decision model has been developed for selecting profitable site-specific herbicide applications in winter wheat. The model is based on six years of field research in southeastern Washington State, USA. The model calibrates herbicide applications to management unit weed densities, soil organic matter, soil moisture, and preceding management, as well as to expected in...

This paper investigates the application of an electrochemical technique for the removal of a common herbicide, bentazone, from water streams using a carbon-based electrode. Activated carbon cloth with high surface area and narrow micropores was used as electrode. For a better understanding of the process, adsorption was investigated under both open circuit and controlled polarization conditions...

experiment was conducted in 2011 to evaluate the efficacy of reduced herbicide rates in combination with false seedbed for selective weed control in common bean. the experiment was carried out with a completely randomized factorial design. factors were herbicide dose (post-emergence application of imazethapyr at the rates of 0, 25, 50, 75, and 100 g a.i. ha-1) and seedbed preparation (false see...

Gromoxone 267 SL Herbicide (GH) is widely used in weed control, and its contamination the soil has potential for agricultural land. The purpose of this study was to explore effect application soluble herbicide on changes chemical properties Inceptisols. This a completely randomized design with 4 treatments 3 replications, namely A = 0% R (0.00 mL GH 7.34 H2O); B 50% (0.03 mL-1 C 100% (0.06 HG H...

In sub-Saharan Africa rain-fed agriculture cropping system uses a limited agricultural technology, occupies more than 95% of cultivated land. The impact of meteorological drivers on crop yields, and, in addition, the effects of herbicide application on farm productivity were examined at two locations; with a 70km distance between them, El Mazmum and El Dali in semi-arid Sudan. For ten successiv...

The short-term effects of the herbicide glyphosate (1.25-10 mM) on the growth, nitrogen fixation, carbohydrate metabolism, and shikimate pathway were investigated in leaves and nodules of nodulated lupine plants. All glyphosate treatments decreased nitrogenase activity rapidly (24 h) after application, even at the lowest and sublethal dose used (1.25 mM). This early effect on nitrogenase could ...

Imisun and CLPlus are two imidazolinone tolerance traits in sunflower (Helianthus annuus L.) determined by the expression of two alleles at the locus Ahasl1. Both traits differed in their tolerance level to imazapyr -a type of imidazolinone herbicide- when aboveground biomass is considered, but the concomitant herbicide effect over the root system has not been reported. The objective of this wo...

We compared the seedbanks, seed rains, plant densities and biomasses of weeds under two contrasting systems of management in beet, maize and spring oilseed rape. Weed seedbank and plant density were measured at the same locations in two subsequent seasons. About 60 fields were sown with each crop. Each field was split, one half being sown with a conventional variety managed according to the far...
