Soil-borne diseases present an ongoing challenge to the Australian vegetable industry, with an estimated $120 million in losses annually.
Soil-borne diseases may be caused by fungi, bacteria, water moulds, nematodes and viruses living in the soil. These pathogens are able to survive for long periods on plant debris, organic matter or sometimes as free-living organisms, i.e. not requiring a plant host. The ability to survive for long periods in the soil, and often having a wide host range, makes control of soil-borne diseases difficult.
Phosphorus (P) is a major element (macronutrient) that plays a number of important roles in plants, such as productivity, crop quality, increased root growth, and earlier crop maturity. It is necessary for proper cell division and formation of new cells. It's important that soil P is managed correctly for crop nutrition.
This factsheet covers the common characteristics of soil P and its availability for uptake by plants such as pH, mobility and microbial activity, and provides practical management tips and tools in line with the ‘4Rs’ - right source at the right rate, right time, right place.
Knowing how wet or dry your subsoil moisture will help make decisions around when to start or increase irrigation, when to terminate cover crops, and how much "insurance water" you have in your soil.
Crop water use can increase by more than 400% in spring - early summer due to rapid crop growth combined with increases in seasonal water demand (ETo). Be prepared for the increase in irrigation demand.
Make sure your crop monitoring and soil moisture tools are working before it really warms up and crops really get going.
A check of your irrigation system will ensure you are ready to start irrigating on time and are set-up well for the season ahead.
This checklist, while developed for K-Line systems, is applicable to most irrigation systems used in vegetable production. Use it as a guide to your irrigation system check.
Vegetable crop diseases are often caused by fungi. Examples of foliar diseases caused by fungi include: downy mildew, powdery mildew and white blister. Examples of soilborne fungal diseases include: clubroot and diseases cause by Pythium, Fusarium, Rhizoctonia, Sclerotinia and Sclerotium species.
Fungicide resistance occurs when a fungicide or active-ingredient that was once effective, becomes no longer effective. It can occur when reduced rates of fungicides are used or when fungicides are over-used.
Read this fact sheet to find out more about detection and effective management.
When irrigating vegetable crops, the use of poor water quality can affect both the crop and soil in which the plants are growing.
Water analysis is a valuable tool for determining potential or existing salinity problems, developing irrigation strategies, and verifying toxicities or mineral imbalances.
This fact sheet covers the water quality parameters you should know about, like salinity, sodicity, calcium carbonate and other macronutrients.

Can calcium cyanamide (Ca(CN)2) fertiliser affect Pythium spp. and other soilborne diseases in carrots – findings of an on-farm demonstration
Calcium cyanamide (Ca(CN)2) fertiliser was tested for efficacy against Pythium sulcatum and P. violae in a grower led demonstration trial in a commercial carrot crop in Western Australia. The wax coated fertiliser was applied according to manufacturer’s instructions at 300 kg/ha and 500 kg/ha of fertiliser to one full length carrot bed each. An untreated bed adjacent to each treated bed was used as control. All standard commercial crop management inputs were applied consistently to treated and control beds. This included nitrogen fertilisers.
This report presents findings from a grower led, on-farm demonstration trial. Grower led pilot trials provide preliminary feasibility assessments of new practices. They can lead to on-farm adaptation of practices and/or replicated research trials to rigorously test assumptions made because of initial findings.

Since 2016 there have been numerous customer complaints about redback spiders (Latrodectus hasselti) in broccoli. Complaints have mainly come between January and June, and from customers in all Australian states. This suggests that this is not an issue for a single production area, but can occur anywhere that broccoli is grown.
Redback spiders are clearly unacceptable to consumers, and also pose risks to growers, pickers and packers.
Despite their fearsome reputation, redback spiders are generally timid. They are nocturnal, travel only short distances and need protection from wind, rain and extremes of temperatures. Broccoli crops are not their usual habitat.
This fact sheet summarises what we know about the risk of redback spiders contaminating broccoli.

Fusarium is a genus of common soilborne fungi. Most live as saprophytes on decaying plant matter while a few are also important plant pathogens.
While there are many different pathogenic Fusarium species, some of the most damaging diseases are caused by strains of one species complex, Fusarium oxysporum. They cause vascular wilt diseases by entering the roots and colonising the water-conducting tissue (xylem). This causes older leaves to yellow and plants eventually wilt and die.
For more information read this practical fact sheet on fusarium wilt diseases, factors that favour fusarium diseases, and management strategies.

This case study outlines the economic considerations when using compost in vegetable production systems. It is based on lessons learned from several Soil Wealth and Integrated Crop Protection (ICP) demonstration sites, during the period 2014 to 2016.
The costs of compost are largely driven by the type and quality of the compost; freight costs depends on distance; and spreading/incorporation costs depend on application rates, type of compost, machinery required, travelling time and the scale of the work.
The benefits will depend on the individual farm as well as the objectives for using compost, for example increase organic matter or prevent be collapse. The main benefits of using compost are increased organic matter, adding nutrients to the soil, increased water holding capacity of the soil, and disease suppression. It is important to consider other practices that may need to change in conjunction with compost application, such as tillage, irrigation and crop protection requirements.
This case study outlines the economic considerations when using cover crops in vegetable production systems. It is based on lessons learned from several Soil Wealth – ICP demonstration sites, during the period 2014 to 2016.
One of the most important considerations is being clear about the purpose of using cover crops in the farm system system as it influences the way you may judge costs and benefits and the timing of these.
The overall benefits will depend on each situation. However, to figure out what works for you on your farm and a specific purpose, talk to others who have used cover crops for a similar purpose / situation; trial cover crops or include a test strip if possible.

Two Pythium species are mostly responsible for forking and cavity spot of carrots in Australia. In most cases, P. sulcatum cause the symptoms.
While some general rules apply, especially the need for managing soil moisture, pH, soil calcium and crop maturity; carrot producers should find their own optimum combination of additional management strategies that fit their production systems and growing conditions.
Read this useful fact sheet to find out more about what causes cavity spot and forking in carrots, as well factors affecting cavity spot development and management approaches.
The purpose of this guide is to help growers and agronomists interpret conventional ‘chemical’ soil tests and identify soil chemical constraints for commercial vegetable production in Australia.
This resource can be used to guide site specific decisions on nutrition management. It does NOT provide prescriptive information on how much of a certain nutrient or fertiliser to apply to various vegetable crops. A recipe approach is not recommended because results in crop performance would be unreliable.
A soil test, combined with a visual soil assessment, and knowledge about paddock history and production plans, provides a sound basis for a nutrition program.

Anhydrous ammonia has long been used as a preplant and side dressing fertiliser in the cotton and grain industries. It results in a high retention of nitrogen in the soil, reduced leaching of nitrates through the soil and yield increases in various crops. However, it needs to be treated with care as it can cause injury to farm workers.
Anhydrous ammonia has beneficial effects on soil microbes, nitrifying bacteria and worms. It is more suited to row crops rather than babyleaf crops, where even distribution nitrogen in the soil is required.
Implementing IPM on farm - experiences from leading growers: Peter Schreurs and Sons, Devon Meadows VIC
Peter Schreurs and Sons grow a range of vegetable crops on their 180 hectare farm in Devon Meadows near Cranbourne in Victoria. Leeks are the main crop in the business, but they also produce cos lettuce, endive, kohl-rabi, wombok and radicchio.
On the farm, Darren Schreurs is responsible for controlling pest and disease in the crops. Darren first encountered Integrated Pest Management (IPM) when he was trying to deal with mites and thrips in their leek crop.

Plant nutrients are commonly split into two categories:
• Major elements (macronutrients) that are required in relatively large quantities by plants, and
• Trace elements (micronutrients) that are essential for plant growth, but are only required in small amounts.
All elements must be available in a form that is useable by the plant, and in balanced concentrations that allow optimum plant growth.
Download this great summary of what the plant nutrients do, and how they need to be applied for the plant to make best use of your investment in fertilisers.
Soil sampling and testing is usually done prior to planting a crop; specific in-crop testing can be useful e.g. testing for available nitrate and ammonium.
A soil test report is only as good as the care taken in sampling. Tools and equipment should be cleaned prior to collecting each sample. Completing labels and writing on bags or containers before going out to the field can save some time and confusion.
Read this fact sheet for guidance on how to take soil samples correctly and obtain reliable information on the nutrient status of your soil.
This summary provides Australian vegetable growers with an understanding of available and emerging irrigation practices and technologies that could improve profitability and encourage the uptake of more efficient water practices.

Maintaining or increasing soil carbon makes good sense – for the environment and for soil productivity. While climate scientists talk about soil carbon, you will know it better as soil organic matter. And the productivity benefits of soil organic matter are legendary:
• Providing a slow release supply of nutrients
• Improving cation exchange capacity and nutrient- holding ability
• Buffering against soil acidity
• Improving soil structure and aggregate stability
• Improving soil water holding capacity
• Reducing erosion risk.
This fact sheet summaries the opportunities and management options for mitigating or sequestering soil carbon in vegetable soils.

One of the key issues with babyleaf spinach is how to deliver this popular leafy vegetable to consumers in good condition. For this to happen, growers must first produce high quality spinach, and this quality must be maintained throughout the supply chain until it’s used by the consumer.
This fact sheet explores the three most significant pre-harvest factors that affect spinach post-harvest quality and shelf-life. These are growth rate of crop, variety, and minimum night temperature during the growing period.
Lettuce is an important horticultural crop in Australia, with an annual production over 160 million tonnes and a total gross value of $140 million. Lettuce is regularly purchased by 80% of consumers in Australia.
The key quality attributes for whole and fresh-cut lettuce are moisture loss, shrivelling, colour (browning, bleaching of the green colour), off-odours, and off-flavour formation, breakdown and microbiological contamination.
This fact sheet will assist you to address these key quality attributes through important pre-harvest crop management such as developing a crop planting schedule, mineral nutrition, tip burn management, deficit irrigation, floating row covers and light.
A healthy topsoil is a great asset to have, as this layer of soil contains the highest concentration of organic matter, micro-organisms, nutrients and biological activity. Lost topsoil can’t be replaced in a human’s lifespan. Therefore erosion, probably the biggest culprit in the loss of topsoil, should be effectively managed.
This fact sheet provides essential information on managing soil erosion, including reducing the impact of wind and water. The easy to read publication also guides decision-making on managing your irrigation system, controlling run-off water, covering exposed soil areas, improving soil structure and increasing cohesion between soil particles.

Internal rot in capsicum is an infection on the seeds, placenta or internal wall(s) of capsicum red fruit. Normally, symptoms are only seen once the fruit is cut open. The external appearance of the fruit is completely normal.
The disease leads to downgrades and rejections of fruit on the market, and affected fruit often progress right through the supply chain, to consumers.
The purpose of this factsheet is to bring together the most up to date information on the cause(s), control and prevention of internal rot in capsicums.
Insects are potential contaminants of processed leafy vegetables. Pest and beneficial species, in both the juvenile and adult stages of their life cycles can become unwanted contaminants if they make their way from the field into the final packaged product and to the end consumer.
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.
