The world of agriculture is a delicate dance with nature, and this season's crop watch has been a testament to that. From the North to the South, farmers and agronomists have been navigating a challenging path, with weather conditions playing a pivotal role in crop health and disease management.
Unsettled Weather, Unsettled Crops
The shift from dry and warm to mild and wet has brought a host of issues. In winter wheat, the dry spell between T1 and T2 offered a respite from septoria, but it also allowed yellow rust to thrive in susceptible varieties. The challenge lies in the timing of sprays, dictated by the weather, and missing a window can lead to more complex management.
A Balancing Act
Spring crops, while benefiting from the rain, face increased weed and disease pressure. Early plant growth regulators and manganese treatments have been effective, but the focus now shifts to weed control and disease management as crops enter stem extension. Maize, too, has its own set of challenges. Warmer and wetter conditions promote early growth, but farmers must navigate precise timing for post-emergence applications and weed control.
Pea Protection and Aphid Alert
Peas are in full bloom, and high aphid numbers have been a cause for concern. Treatment strategies have been employed, and the presence of ladybirds and hoverflies offers a natural solution. The aphid population's resistance to pyrethroids and pirimicarb has led to the use of alternate products, highlighting the importance of varied pest management approaches.
Fusarium and Rust: A Double Threat
In wheat, the early flowering due to high temperatures has brought forward T3 fungicide applications to prevent fusarium infection. Rust, however, remains a primary concern, especially in susceptible varieties. The decision to apply pod sealant in oilseed rape is a delicate one, influenced by grower opinion and the crop's stage of growth.
Spring Cereals: Struggling to Keep Up
Spring cereals, particularly barley, have suffered from the recent weather. Lack of tillers and rapid growth stages have left many crops stunted. The focus now is on weed control and disease management, with limited potential for further interventions.
Maize: A Mixed Bag
Maize crops are showing promise, with the weather setting them up nicely for the season. However, the presence of black bindweed requires a different treatment strategy, and addressing nutrient deficiencies and disease issues is vital. The challenge lies in implementing cultural and chemical controls to reduce disease impact in the current and future seasons.
Sugar Beet and Potato Concerns
Sugar beet crops vary widely, with some achieving canopy closure before the longest day and others struggling to emerge. Beet moth, a newly emerged pest, has been observed, and emergency authorization for its control has been granted. In potatoes, the risk of blight is high, with several Hutton periods predicted. The key lies in appropriate product choice and maintaining robust spray intervals.
A Season of Reflection
As farm visits shorten and conversations turn to the next season, the trials and tribulations of this year become a learning curve. The extreme weather conditions have tested the resilience of crops and farmers alike, and the insights gained will shape future strategies.
In my opinion, this season's crop watch serves as a reminder of the intricate relationship between agriculture and nature. It's a constant dance, and the steps must be adapted to the rhythm of the weather. The challenges faced this season highlight the importance of varied management strategies, from pest control to disease management, and the need for a deep understanding of crop stages and thresholds. It's a fascinating and ever-evolving field, and I, for one, am eager to see how the lessons learned this year will shape the future of agriculture.
