Impacts of Temperature

The importance of the environment on the development of plant diseases, pests and weed has been known for over two thousand years. Climate change may cause significant impacts on Brazilian agriculture particularly on the occurrence of diseases, pests and weeds. The temperature is considered one of the main climatic variables that will change. However, the impacts of high temperatures on the health problems of crops in different regions of the country are not known.

For the assessment of the impacts of high temperatures, it is important to understand how this variable will affect the plant physiology and the interaction between pathogen/insect and plant. Studies about the influence of temperature on the incidence/severity of pests, diseases and weeds under growth chamber provides data that explain the development and impact in the field. The experiments will be performed in growth chambers with temperature levels based on the IPCC predictions.
