In the first week of August, the average price of washed Agata-type potatoes stood at R $ 91.11 (weighted by their classification), i.e. 69.6 % higher than the R $ 53.70 price of the week of July 21. The price increase was caused by the recent frosts that affected most of the producing areas. The losses haven't been accurately measured yet, but Hortifruti/Cepea are making progress in their quantification.
According to estimates, the region of Perdizes (Minas Gerais) - which concentrates a large part of the production of the Cerrado Mineiro where the winter harvest is harvested - had losses that range between 10% and 15% of the total crops under development, with greater damage due to frosts in the week of July 19 to 23. Estimates are that the other municipalities of the Cerrado de Minas Gerais had higher losses that range around 30%. In addition, producers have observed a higher incidence of thrips in tubers, which could end up affecting productivity even more in August and September.
The production areas in the southwest of São Paulo, in turn, were severely affected by the July frosts. As such, their losses are greater than in other regions and are estimated between 30% and 50%. In Vargem Grande do Sul they are close to 35%. The rains of the last few days and the cold weather in the regions of São Paulo are forcing producers to use higher levels of fumigation, with systemic fungicides to control late blight, as the high humidity and low temperatures favor the development of this pathogen.
Finally, the losses in southern Minas caused by the frosts that took place between July 29 and July 30 have been quantified yet, but it is estimated that they could amount to 30%. The biggest impact on production should occur between the second half of this month and early October.
