Managing stubbles post-harvest is an ongoing issue that growers deal with every year in their cropping rotation. OFT contains more than 400 trials on stubble retention, management and benefits. There are over 180 published stubble management trials for wheat, 40 for barley and 35 for canola.
Many different strategies exist to conserve soil moisture pre and post sowing including spraying and tillage. There are over 150 trials in Online Farm Trials covering issues that include: managing moisture variability; crop rotations that optimise moisture availability; impacts of break and summer crops; and, nitrogen conservation, including timing of fertiliser application.
Belonging to the species Chloris Virgata, Feathertop Rhodes Grass (FTR) is a major weed that plagues broadacre cropping systems accross Australia.It is a tufted grass that can grow up to 1M tall. They have semi-prostrate stems, blueish-green leaf blades and feathery seed-head spikes. FTR is not verly susceptible to glyphosate herbicide, particularly after the early tillering stage.
Blackleg is a sexually reproducing pathogen that will overcome cultivar resistance genes. Fungal spores are released from canola stubble and spread. This bookmark filters on Canola fungicide trials in the sourthern region.
Fall Armyworms are caterpillar like pests that affect cereal crops by feeding on the leaves, and in some cases, on the stems. There are 3 common types of armyworm namely : common armyworm (Mythimna convecta); southern armyworm (Persectania ewingii) and inland armyworm (Persectania dyscrita). Seasons for these range from summer right through to winter and early spring. Young larvae feed on leaf surfaces but as they grow and the season progresses, the larger caterpillars feed on complete leaves and tillers. Once foliage dies off, they will eat through any green areas that remain. Early detection is essential.
