The Buenos Aires Grain Exchange has reduced its corn production forecast for Argentina by 2.5 million tons, bringing the new estimate to 54.0 million tons. This adjustment is primarily due to the adverse effects of corn leafhoppers and the spread of corn stunt disease, which is caused by the bacterium Spiroplasma kunkelii. Despite only 3.7% of the corn crop being harvested so far, with yields averaging 8,690 kg/ha and peaking at 9,820 kg/ha in the northern core region, the overall condition of the corn crop has suffered. Currently, 21% of the crop is rated as poor/very poor, 55% as fair, and 24% as good/excellent. The spread of corn stunt disease, facilitated by corn leafhoppers, has been a significant factor in the lowered crop ratings and yield projections.
