CropsRyegrass in the Swartland wheat belt is the best-known case. Agronomists from Corteva, Syngenta, CropLife and the University of Adelaide say rotating modes of action alone will not stop resistance.
CropsJohn Innes Centre researchers trained 21 Tanzanian scientists to use a low-cost LAMP assay that turns from pink to yellow when wheat blast is present, as the disease spreads in neighbouring Zambia.
AgribusinessDisrupted shipping, high energy and fertiliser prices and the risk of El Nino drought cutting grain output could push world food prices higher still; FAO's Food Price Index averaged 136 points in September, its highest since November 2022.
Wheat stays at 9.64 million tonnes, corn at 7.2 million, rice at 5.32 million and fertiliser at 13.65 million tonnes, while soybean buying from the US continues outside the quota system.
CropsRothamsted traps show more than half of bird cherry-oat aphids winged and nearly 40% carrying virus, and AHDB's new BYDV model puts the cost of an untreated early-drilled wheat crop at £90-210/ha.
CropsA Nature Food study led by Chinese researchers with NASA finds widely used models underestimate how much droughts, heatwaves and the two together already cut wheat, and that irrigation's protective effect is weakening.
CropsProvisional Defra figures put English barley production at 3.7m tonnes, down 11%, and wheat at 10.8m tonnes, up 0.8%, while feed barley trades at a wide discount to wheat.
CropsRabobank forecasts a 2026/27 Australian winter crop of 62.9 million tonnes, 7.9 percent below last season but above the five-year average, with dry northern regions offset by strong crops in South Australia and Victoria and a record canola harvest.
CropsOntario's Jeff Cook topped the 2025-26 Great Lakes Yield Enhancement Network with 163.2 bushels per acre and Laurent Van Arkel reached 108% of his field's yield potential, while participants averaged 112 bushels per acre in a difficult season.
CropsWith Agriculture Canada pulling out of late-stage variety work, farm groups are weighing Australia's levy-and-match system, the US mix of universities and companies, and Brazil's public Embrapa model.
CropsThe British Crop Production Council's October update lists new Syngenta and BASF fungicide combinations for cereals and two FMC cyantraniliprole products for potatoes and carrots ahead of 2027.
CropsOf 208 field experiments since 1983, just 21 had the data to judge water productivity properly, and the real variation was far smaller than the claimed 20-40% savings suggest.
CropsIn Sonora, Mexico, a CIMMYT and Grupo Trimex programme combining conservation agriculture, soil-tested fertilizer and better irrigation raised wheat yields from 3 to 4 tonnes a hectare while using less water, fuel and nitrogen per tonne.
