AgNow Roundup: Weather and Insect Pressures on Crops
Matt Makens provided a detailed weather report, indicating that cold weather is moving across the country. The forecast from January 20th to 27th suggests most moisture will be over the west initially, with heavier rain expected to reform over the southern plains and Mississippi Valley later on. This is beneficial for drought-stricken areas in central and southern regions from Texas to Kansas eastward.
Precipitation and Snowfall Predictions
The west coast anticipates 7-15 inches of water, which is crucial for water resources.
A similar pattern of heavy rainfall is expected in the southern Mississippi delta, affecting areas from New Orleans to Houston.
Snowfall will mainly benefit the central and northern Rockies, while other areas like the upper Midwest and high plains may experience less precipitation.
Temperature Trends
The end of January into early February will see warmer conditions in the west due to a strong ridge formation. Meanwhile, colder temperatures are predicted to persist in eastern regions.
Insect Pressure on Crops
Canola Challenges
Flea beetles pose a significant threat to canola crops at early stages. Seed treatments are essential for protection against these pests. However, resistance issues have arisen with neonics, necessitating newer chemical groups like diamides and butanolides. Delayed planting is advised but may not be effective due to high beetle populations.
Soybeans and Other Crops
Soybeans faced fewer insect problems compared to other crops this year. Chinchbugs were notable in corn and sorghum systems but had less impact on soybeans once they matured. Grasshoppers presented some foliar feeding challenges exacerbated by hot and dry conditions.
Sugar Beets Concerns
The sugar beet root maggot damages roots during springtime development, potentially causing stand loss if unmanaged. Another issue comes from a plant bug affecting foliage which can also lead to disease.
Rice Crop Conditions
In California's climate, rice crops face minimal disease and insect pressures. Army worms can occasionally be problematic along with tadpole shrimp that damage young rice roots in water-seeded systems.
