BYDV is a complex, aphid-transmitted disease that poses significant risks to cereal production in New Zealand. Find out more about the disease in this update.

A T1 fungicide can be the hardest application to get right. Ideally, it targets GS 32 (leaf 3 emergence, two leaves below the flag), but getting the timing right can be challenging if conditions are wet and/or windy. FAR has extended the T1 window to late GS 31- GS 33 find out more here.

Micronutrients are essential trace elements required by plants in very small quantities (mg/kg dry matter). They are critical for normal plant growth, development, and reproduction. Find out more about micronutrients here.

This Arable Extra covers tips for spring nutrient requirements including nitrogen, phosphorus, potassium, sulphur and magnesium. 

This fact sheet outlines the differences between urea, urease inhibitors, polymer coated urea (PCU), nitrification inhibitors, calcined ammonium nitrate, ammonium sulphate or sulphate of ammonia and compound fertilisers.

If you missed the WeedSmart NZ workshops with Danish weed management expert Mette Sonderskov you can catch up on the booklet here.

Row spacing is an important management strategy in white clover (Trifolium repens) seed crops. Stolons grow outward from the crown of the plant into the space between rows. Nodes produced along the stolon bear either vegetative axillary growth (e.g. a branch) or a reproductive leaf-flower combination. The more nodes that are produced per stolon, and subsequently per unit area, the greater opportunity for flower production and thereby seed yield. In theory, wider row spacing should produce more flowers/m2 due to more space for stolon proliferation.

A FAR project is helping arable and dairy farmers understand more about the greenhouse gas emissions associated with growing and using feed wheat, feed barley, maize grain and maize silage.
