Intercellular distribution of enzymes involved in amino nitrogen synthesis was studied in leaves of species representing three C(4) groups, i.e. Sorghum bicolor, Zea mays, Digitaria sanguinalis (NADP malic enzyme type); Panicum miliaceum (NAD malic enzyme type); and Panicum maximum (phosphoenolpyruvate carboxykinase type). Nitrate reductase, nitrite reductase, glutamine synthetase, and glutamat...

The commercial release of transgenicmaizewith resistance to rootworms incorporated with glyphosate tolerance has become a reality, and questions have arisen regarding the impact of grassy weed phenology on the biology of the western corn rootworm, Diabrotica virgifera virgifera LeConte. A study to determine the impact of host plant phenology on the survivorship (percentage larval recovery), gro...

Plant invasions are closely related to environmental filtering and biointeractions; however, the variations in invasive plant niches along latitudinal gradients heterogeneous habitats remain unclear. In this study, we conducted a two-year survey China spanning 21° N–37° N explore niche characteristics of species within communities invaded by amphibious alien weed Alternanthera philoxeroides bot...

Abstract The loss of important contact herbicides like paraquat opens opportunities for more potentially sustainable solutions demanded by consumers and organizations. Frequently, adequate weed control, the alternatives to classical synthetic products need well-defined executed labels even detailed use descriptions. One novel candidate with rare activity is a pelargonic acid ester methyl polyet...

The objective was to evaluate weed phytosociology and similarities between crop management systems in the Chapadões region. experiment conducted at agricultural area located municipality of Chapadão do Sul, MS, during 2016/17 harvest. Three managements strategies were used: (1) cotton/soybean/Urochloa, (2) millet/soybean/millet (3) millet/soybean/crotalaria. A phytosociological survey weeds car...

For optimum postemergence crabgrass (Digitaria spp.) control, a single quinclorac herbicide application could be properly timed and delivered with spray nozzles that produce droplets ranging from very coarse (401-500 μm) to medium (226-325 in size maximize target coverage minimize the potential for drift. Crabgrass is an invasive annual grass weed of cool-season turfgrass maintain as lawns, gol...

The advancements in fodder maize cultivation practices over the past few years, has paved a change makeup of weed associations. This made it necessary to incorporate new, effective herbicides struggle against maize's primary weeds. Therefore, field experiment was conducted at Research Farm, AICRP on Forage Crops, Department Agronomy, JNKVV, Jabalpur (Madhya Pradesh) during Kharif season 2019 de...
