Delayed wheat harvest leads to widespread rodent infestation in Russian fields

Delays in Russia’s wheat harvest in 2026 created favorable conditions for the widespread proliferation of rodents on agricultural land. Diesel fuel shortages and rising fuel prices, combined with prolonged rainfall in some regions, forced some farms to complete harvesting later than planned. During this period, part of the grain was shed onto the ground, leaving substantial amounts of spilled grain, volunteer wheat, and crop residues in the fields after harvesting. These provided an additional food source for rodents and created favorable conditions for population growth.

The scale of the problem is reflected in the results of autumn monitoring by Russia’s Federal Agricultural Center (Rosselkhozcenter). In 2026, rodents were detected on 966.85 thsd ha out of 2.06 mln ha of surveyed agricultural land, representing nearly 47% of the inspected area. However, the actual extent of the infestation could be significantly greater than official figures suggest, as the possibility that Russian authorities are downplaying the severity of the problem and its potential consequences for future harvests cannot be ruled out.

The growing rodent population poses the greatest threat to winter crops planted for the 2027 harvest. Following the completion of grain harvesting, rodents migrate to newly planted fields, where they feed on seeds and damage emerging seedlings. When pest populations are high, large areas of crops may suffer severe damage or complete destruction. Farms where substantial amounts of spilled grain and volunteer wheat remain after harvesting, and where rodent control measures were not implemented promptly, are particularly vulnerable.

As a result, the consequences of Russia’s delayed harvest extend well beyond grain losses in the current season. Fuel shortages and adverse weather conditions that disrupted timely wheat harvesting are now accompanied by additional risks to winter crops from spreading rodent populations. Against a backdrop of low procurement prices, high production costs, and logistical difficulties, the need for intensified pest control is placing further financial pressure on farmers.
