The objective of the work was to evaluate the effect of insecticide and fungicide in the treatment of wheat seeds. The treatments were, T1: control, T2: thiamethoxam (1.5 ml / kg of seed), T3: thiamethoxam (3 ml / kg of seed), T4: pyraclostrobin + methyl thiophanate + fipronil (PTF) (2.0 ml / kg of seed) and T5: PTF (4.0 ml / kg of seed). The treatment with TPF in the dose of 4.0 ml / kg of seed stood out over the other treatments, providing positive effects on the development of the culture, since thiametoxam in the dose of 3.5 ml / kg of seed, showing no difference between treatments, and provided a negative effect on the initial development of the plants.

A research aims to study and analyze which factors contribute to grain losses in the transport logistics chain. For this purpose, a descriptive research was carried out, through the application of a questionnaire, involving aspects related to transport logistics. The results indicate that, for the interviewees, the factors that most contribute to the loss of grains in the transport logistics chain are the use of vehicles in inadequate transport conditions, and that do not have adequate maintenance of the bodies. In addition, the factors least related to losses are the lack of tire calibration and the short scheduling windows for unloading grains at ports.
