Guide to Brassica Biofumigant Cover Crops: Managing soilborne diseases in vegetable production systems
This publication contains information to assist growers in understanding how biofumigants work and managing them for optimum efficacy against soilborne diseases.
Biofumigants are a unique type of cover crop that produce compounds with suppression effects on soilborne pathogens, pests and weeds.
This guide also discusses and presents data on a range of agronomic management practices of biofumigant cover crops including pest and diseases, nutrient uptake requirements, irrigation and incorporation methods.

IWM on a Bathurst pumpkin farm: Advantages & drawbacks of ground cover use, tillage and residual herbicides
Grey pumpkins (var. Sampson) were planted the week of 4 November 2019, following strip tillage of terminated ryecorn and conventional tillage (rotary hoe) of terminated oats and vetch cover crop areas respectively. Clomazone herbicide was applied post- sowing pre-emergent (PSPE) at a rate of 0.4 kg a.i./ha and incorporated immediately with 25 mm irrigation water. A small control area was left untreated (no herbicide), both for the strip tilled ryecorn and conventionally tilled oats and vetch cover crop areas. A month post-sowing, most of the conventionally tilled area was inter-row cultivated.

Recent surveys of Tasmanian ryegrass (Lolium spp.) populations have shown a significant increase in Group A herbicide resistance. John Broster (Charles Sturt University) found an increase in resistance from 18% in 2010 to 46% in 2015 to diclofop-methyl ‘Fop’ and sethoxydim ‘Dim’ herbicides.
The selection of resistant weeds can occur in just 3-4 years if herbicide groups (Modes of Action) are not rotated. Read this fact sheet for an overview of herbicide resistance and what you can do to avoid and minimise the risk of resistance developing.
Biosecurity planning provides a mechanism for the vegetable industry, government and other relevant stakeholders to actively determine pests of high priority, analyse the risks they pose and implement procedures to reduce the chance of pests becoming established. AUSVEG delivers a number of extension projects with a core biosecurity focus, in addition to project partners like Plant Health Australia.
Most new technology for controlling weeds will be a positive step forward for soil health and the environment, and will play an important role in our fight against herbicide resistant weeds.

Adjuvants are additives that enhance or modify the action of a chemical. They are commonly classified into broad categories including oils, surfactants, buffers, acidifiers and fertiliser adjuvants. Adjuvants can modify how a chemical forms, spreads or behaves within the spray solution and/or on the target pest.
This fact sheet provides insights into how adjuvants work, what types are available, and recommendations on what one to choose to make sure it's compatible with your pesticides active ingredients.
Pesticide resistance is an ongoing concern for the vegetable industry.

Weeds increase the cost of growing vegetables, reduce crop yield and quality, and impact farm management decisions, such as timing of harvest and choice of herbicide options.
Biofumigation is the use of specialised cover crops, which are grown, mulched and incorporated into the soil prior to cropping. High biomass, especially roots, can provide the traditional benefits of green manure crops, and if done right, naturally occurring compounds from the biofumigant plants can suppress soil-borne pests, diseases and weeds.

A reduced till system on this Cowra vegetable farm delivered soil, cost and crop benefits.
NSW farmers, Ed and James Fagan explain how they developed a reduced tillage vegetable farming operation in Cowra, NSW.
Reduced till is a system change that relies on keeping the soil in a healthy condition through the use of permanent beds, controlled traffic, cover cropping and crop rotations rather than frequent cultivation.
Specialists in all areas of brassica production, including insect, disease, nematode, weed and virus have combined to pool current knowledge on best practice IPM principles.
Rather than prescriptive rules for each problem, the information provides knowledge and general principles that you can use to plan for an integrated approach to crop production.
This guide has been produced in conjunction with participating greenhouse growers to provide a practical guide to help you to economically and effectively introduce preventative and integrated control strategies to manage pests and diseases in your greenhouses.
