In Bolivia, more than 70% of wheat production is grown on the eastern lowlands of Santa Cruz Department. Wheat is an important winter crop grown after the summer soybean crop. In early sown wheat (15 April-10 May), environmental conditions prevailing in the humid and intermediate areas of the region are very favorable for development of spot blotch, caused by Bipolaris sorokiniana. Yield losses of up to 57% have been observed but are highly dependent on planting date, wheat variety, and climatic conditions. Optimum time for fungicide treatment is 15 days after first observation of symptoms, which corresponds to heading stage for normal sowing times (May).
