1. Thiamethoxan on sugar cane, common bean, soybean, citrus and coffee plants: parameters of development and biochemical aspects / Tiametoxam em plantas de cana-de-açúcar, feijoeiro, soja, laranjeira e cafeeiro: parâmetros de desenvolvimento e aspectos bioquímicos
Insecticides and fungicides are often studied to their efficiency in controlling pests and diseases, however can cause physiological effects little known that can affect crop growth. Thiamethoxan is a systemic insecticide from the neonicotinoid group, nitroguanidine family, which acts on nicotinic acetylcholine receptor of insects, damaging their nervous sys

3. Nutritional efficiency of sugar cane cultivars / Eficiência nutricional de cultivares de cana-de-açúcar
This work aimed to determine the nutritional efficiency of sugar cane cultivars in the first two crop-growth cycles (plant and first-ratoon crops). Thus, biological utilization coefficient and apparent sucrose yield ha-1 (TPH) were evaluated. The experiment was set up on mid February 2003 in a clayey textured Red Yellow Argisol, and arranged in a randomized

4. Epidemiology and management of coffee (Coffea arabica L.) diseases under organic farming. / Epidemiologia e manejo de doenÃas do cafeeiro (Coffea arabica L.) sob cultivo orgÃnico
The present work aimed to study coffee diseases on organic crop system. For that, rust and black eye spot disease progress on organic and conventional crop systems were compared. The effect of nutrient sources in the disease management was evaluated and, finally, the effect of plant extracts in the protection of coffees in the organic system was tested. The
