The Need for Herbicide Use in Direct Seeding, Promotes More Sustainable and Implementation of Integrated Systems
Technological advances the Argentine has been in recent years such that now stands at the forefront worldwide. The explosion of agriculture, tillage, GM crops and the widespread use of glyphosate have raised controversy, especially regarding the toxicity of the latter. Before weeds are controlled with tillage and these involve serious problems of erosion and soil degradation. Tillage and herbicides have changed the situation and consequently the sustainability of production systems.
Onion thrips (Thrips tabaci Lindeman) are dual destructive as both pests and vectors of Tospo viruses. Thrips tabaci has impact on a wide range of crops. Thrips damage, thrips count, leaf parameters, tolerance, susceptibility and onion yield of thirteen onion genotypes and three commercial onion cultivars were tested. The results of TAUIPC (Total Area Under Infestation Pressure Curve) showed that the accessions having their average leaf damage below two namely VIO38552, VIO38512 and AVON 1067 were categorized as the most tolerant accessions among the tested genotypes.
This guide covers multiple states and production areas. Pest problems vary across the Southeast. Pesticide rates are a guideline. Exceptions are noted for specific locations and pests, but this guide does not list every exception. Listed pesticides may not be registered for the uses recommended here in all states.
Las razones por las cuales puede presentarse un daño en un cultivo provocado por una intoxicación con agroquímicos son muy variadas; analicemos las más frecuentes.
Efectividad de algunos insecticidas para el control de Bemisia tabaci (Gennadius) en tomate, Solanum lycopersicum L.
Why does a pesticide work well one time and not so well the next when everything seems the same? Variable weather could play a role. Or the pest could be less susceptible to the active ingredient. At other times, an inconsistent pesticide performance seems inexplicable.
Disease and insect control is a critical factor in most commercial vineyards. Whilst such control may, in some seasons, be a small proportion of crop value, there is a demand from growers for increased efficiency of spraying. Attention to detail is necessary to improve efficiency of deposition, reduce drift and increase sprayer output.
