How the development of resistant cultivars can help in the management of stink bugs in soybeans, by helping to reduce the costs of insecticide applications and protecting the longevity of the few molecules available for chemical control
Choosing the soybean sowing date does not entail costs for the producer and modifies the productive potential and water availability throughout the development cycle. Furthermore, it is a strategy to minimize the risk of loss of productivity due to stress.
The definition of a method that makes it possible to distinguish between these two sources of variation in soybean crop productivity is of great use to producers and consultants, as it makes it possible to define the strategies to be adopted to minimize losses.
Since the 2009/10 harvest, soybean crops have manifested symptoms such as wrinkling of the leaf blade, thickening of veins, blackening of leaves, abortion of flowers and pods, poor grain formation and oversprouting. Among the hypotheses to explain this anomaly is the probable potassium deficiency
