Choosing the most effective foliar fungicide disease control strategy can be complex due to differences in variety resistance and impacts from seasonal conditions. OFT contains over 330 trials on fungicides and management strategies including the effects on yield for various crops, managing an array of diseases, fungicide...

Grain production losses due to weeds are estimated to be $3.3Bn with farmer costs of $146/ha (Impacts of weeds on Australian Grain Production). A management tactic to reduce impacts of weeds is to prevent weed seed set. OFT contains more than 80 trials on weed seed control strategies and management...

Managing stubbles post-harvest is an ongoing issue that growers deal with every year in their cropping rotation. OFT contains more than 380 trials on stubble retention, management and benefits. There are over 170 published stubble management trials for wheat, 40 for barley and 35 for canola. There is also a set of more than...

The impacts of frost and minimising variability in seasonal profits can be achieved using a combination of management solutions, tools and information. There are over 120 trials provided through OFT covering issues on frost including: frost tolerant varieties, managing frost risk, strategies to reduce frost damage, impacts...


Managing stubble post-harvest is a yearly issue for planning rotation. OFT trials cover issues including stubble breakdown options, cropping sequencing, sowing configurations and associated costs, grazing and weed management strategies.

Many different strategies exist to conserve soil moisture pre and post sowing including spraying and tillage. There are over 140 trials in Online Farm Trials covering issues on managing moisture variability, crop rotations that optimise moisture availability, impacts of break and summer crops and nitrogen conservation including timing of fertiliser application.

Controlling summer weeds is a key strategy to conserving moisture and nutrients across medium to low rainfall cropping zones of Australia. Herbicide and tillage strategies, combating weed varieties, herbicides and adjuvants, and latest spraying technologies are included.

Soils that suffer from poor infiltration due to structure decline and sodicity can result in significant losses in productivity and decline in plant health. An amendment commonly used to treat such conditions is gypsum (also known as calcium sulfate dehydrate).


How can the ascochyta pathogen be managed given its ability to survive between seasons on infected plant residues? Yield losses from ascochyta infection can be minimised through good management practices, including early and timely intervention with fungicides. OFT contains over 100 trials with results on ascochyta blight, including: strategies for blight control in field peas, blight intervention with fungicides in chickpeas and ascochyta resistant varieties of chickpeas.

In today’s farming systems, weeds are controlled largely by the application of herbicides. Heavy reliance on chemicals, however, has led to issues of herbicide resistance. New trials data and information is available that provides alternative strategies to reduce weeds in crop, including integrated weed management where crop competition can play an important role.
