Catalogue: GRDC Updates (West)
The initial adoption of Flexi-N was driven by the convenience of storage and handling, improved speed and uniformity of application, and reduced labour requirements when applied with pesticides... Crop Updates is a partnership between the Department of Agriculture, Western Australia and the Grains Research & Development Corporation 37.. The trials suggest that applying fungicides in large droplets at water rates between 60-80 L/ha will be beneficial in a range of seasons in the Mingenew area...

Potassium can lessen barley disease impact.. Research has shown that applying potassium early in the growing season to barley crops deficient in this nutrient can help reduce the impact of some foliar leaf diseases and boost yields... Trials showed that applying potassium to crops deficient in this nutrient - eight weeks after seeding - could reduce leaf disease incidence of powdery mildew and net blotches and was profitable, provided there was enough nitrogen for plants to respond to the extra potassium," Dr Brennan said.

The application of potassium (K) fertiliser at rates up to 40 kg/ha of K significantly decreased the percentage of leaf area diseased for spot-type net blotch and powdery mildew of barley... The chloride source significantly reduced the percentage of leaf area diseased at rates of 10 and 20 kg/ha of applied K. The two sources of K (KCl, or K 2SO 4) gave significantly different yield response curves where powdery mildew was present... In regions prone to leaf disease we suggest farmers take soil samples before seeding to determine soil K levels...

Twenty one field experiments were carried out on potassium (K) deficient sandy soils to assess the effect of fertiliser K, as either potassium chloride (KCl - 50% K) or potassium sulphate (K 2 SO 4 - 41% K), on the leaf diseases and grain production of barley crops... In regions prone to leaf diseases, we suggest farmers take soil samples before seeding to determine soil potassium (K) levels... Application of different rates of fertiliser N may change yield responses of barley and responses to applications of fertiliser K and this effect may have influenced leaf disease severity levels reported in this project...
