PR 2025/26 Crop Year: Excessive rain delays corn harvest.

Excessive rainfall in the western and southwestern regions of Paraná has delayed the harvest of the second corn crop and caused losses in grain quality. According to the weekly weather and crop conditions bulletin from the Department of Rural Economy (Deral) of the Secretariat of Agriculture and Supply (Seab), the high humidity has prevented the advancement of harvesters and favored the occurrence of burnt grains, open ears, and sprouting while still on the plants, aggravating the losses already caused by the drought and frosts recorded at the beginning of the cycle.

In the North and Northwest regions, on the other hand, the dry weather allowed for the gradual advancement of the harvest in maturing crops, maintaining good sanitary conditions, despite isolated reports of leaf spots.

For the next soybean harvest, Deral observes a scenario of greater caution among producers. The instability of the international market and the increase in the costs of agricultural inputs should reduce investments in crop fertilization.

In wheat, crops generally show good development, but excess moisture has increased the pressure of fungal diseases and leaf spots in the western and southwestern regions, requiring reinforced phytosanitary management. The report also points to a reduction in cultivated area in some locations due to low profitability, climate risks, and market uncertainties.

The second bean crop is also facing difficulties. While some crops are progressing normally, areas in the West and Southwest are experiencing slow harvesting and significant quality losses due to rain during maturation. In some cases, hailstorms have caused total crop loss.

Among winter crops, barley, oats, and triticale are showing satisfactory development, favored by soil moisture and phytosanitary monitoring. Sorghum is also developing normally, with no significant reports of pests or diseases.

Coffee harvesting is progressing in the North and Northwest regions, benefiting from the dry weather, which favors both fieldwork and bean drying. In sugarcane, harvesting and management operations have resumed after interruptions caused by rain.

The report also records localized damage caused by storms and hail to vegetables and orchards, with destruction of protected structures, losses in tomato crops, and fallen trees. In cassava, producers have reduced the pace of harvesting due to low prices, while the second potato crop shows good development conditions. Forestry operations have been halted in some regions due to traffic difficulties on rural roads, and pastures are maintaining satisfactory development due to good soil moisture.
