Getting the Upper Hand on Downy Mildew

By Mary Ruth McDonald, Kevin Vander Kooi and Zachariah Telfer, University of Guelph; and Dennis Van Dyk, Ontario Ministry of Agriculture, Food and Rural Affairs

D

owny mildew can be a devastating disease of onion. It is also frustratingly difficult to control and predict.

The disease is caused by the “water mold” Peronospora destructor. The term “destructor” in the scientific name gives a hint that other researchers also found it very damaging to the onion crop. At one time the pathogen was classified as a type of fungus, but now it is understood that it belongs to a group that is quite different from fungi. The difference in taxonomy helps to explain why only specific types of fungicides are effective for control of this disease.

One of the problems with monitoring and controlling downy mildew is that no symptoms develop until one to two weeks after leaves have been infected. Infected leaves may be a paler green color, but usually the disease is not noticed until purplish, fuzzy sporulation occurs on otherwise green leaves (Fig. 1). Once sporulation can be seen, it can be almost too late to spray fungicides if the weather remains cool and damp. After sporulation occurs on a leaf, other diseases such as purple blotch (Alternaria porri) (Fig. 2) or Stemphylium leaf blight (Stemphylium vesicarium) may follow.

The disease develops under cool and humid conditions. Spores are produced overnight when temperatures range from 39 to 75 degrees Fahrenheit with very high relative humidity over 95 percent.

High temperatures (over 75 to 80 degrees Fahrenheit) the day before, and rain overnight, will inhibit sporulation. Spores survive for at least three days and will germinate on an onion leaf when there are three to six hours of leaf wetness and temperatures below 79 degrees Fahrenheit.

Thus, fog at night lasting in to the morning often provides perfect conditions for spores to be present and infection to take place. An infected leaf area of less than two-tenths of a square inch can produce 100,000 or more spores!

Fungicide Efficacy Trial

Field trials to evaluate fungicides for the control of onion downy mildew have been conducted at the University of Guelph Muck Crops Research Station in the Holland Marsh, Ontario, Canada, over several years. Some years no disease develops, but the cool, wet weather in 2017 resulted in high disease pressure and a good test of the products. The fungicides in the trial were new products Orondis (oxathiapiprolin) + LI700 and Cueva (copper octanoate) compared to newer products Zampro (ametoctradin

and dimethomorph) + Sylgard, Reason (fenamidone), Revus (mandipropamid) and industry standards Ridomil (mefanoxam), alternated with Aliette (foestyl-Al) and Dithane (mancozeb).

Downy mildew was detected in the Holland Marsh area on July 15, and the first fungicides were applied to the trial on July 18. Lesions were first detected in late July, and the number of lesions per plot was counted on Aug. 4, Aug. 14 and Aug. 21. The number of lesions per plot reached over 200 in the untreated check by Aug. 21. On Aug. 28, the number of lesions per

Downy Mildew plant was assessed on 15 plants per plot (Fig. 3). Differences among the treatments were found at the first assessment and were consistent throughout the season (Fig. 4).

Fungicides Orondis, Dithane, Zampro and Ridomil alternated with Aliette all performed well and had consistently low levels of disease.

Disease Forecasting Model

It was a bit surprising that Dithane was so effective, but this demonstrates the value of applying fungicides early, before infection takes place. Since protective sprays are so important, disease forecasting is essential for good control of onion downy mildew, at least in regions with variable weather such as the Holland Marsh. Since downy mildew-specific fungicides are typically more expensive, it is to the grower’s advantage to spray only when necessary. Disease forecasting allows growers to know when disease risk is high

or when it is unnecessary to spray downy mildew-specific products.

In regions of intense onion production, downy mildew acts as a community disease with infected neighboring fields providing significant disease pressure.

The Muck Crops Research Station runs the downy mildew forecasting model DOWNCAST for onion growers in the area.

Over the past few years, the experience with the model has been mixed. In 2014, downy mildew was first found 10 days after DOWNCAST predicted nearly two weeks of optimal disease conditions. This was consistent with disease development (lesions showing up one to two weeks after infection), and it gave growers an early warning to protect their crop. In 2015, downy mildew showed up two weeks after DOWNCAST predicted three days of optimal conditions, again proving that the forecasting program was working well.

The 2016 season was very hot and dry, which makes for unfavorable conditions for downy mildew development. Under these conditions, the model again worked well, predicting that downy mildew was not active and sprays were not needed.

In 2017, the weather was extremely wet and quite cool, and downy mildew development was expected. However, the model did not to predict downy mildew activity until days after downy mildew was already observed in fields. From examining the model, it appears it may have overestimated the necessary relative humidity needed.

Over the next few years, we will be re-examining the model to ensure we can provide timely, predictive forecasting so fungicides can be applied at the right time to control downy mildew. The combination of effective fungicides and accurate disease forecasting can protect the onion crop from this devastating disease.

point that growers must rely on the H-2A guest worker program.

Researchers with the University of Georgia are involved in trialing two newer styles of mechanized planters. The growers challenged the University of Georgia Cooperative Extension service to evaluate some alternatives to hand labor in order to provide scientific data and cost/benefit analysis for the producers.

Two options were chosen to evaluate: 1) PlantTape transplanters and 2) vacuum set planters. The goal was to bring in both types of planters and plant trials at the Vidalia Onion and Vegetable Research Center as well as in grower fields. The university extension specialists will evaluate fertilizer rates, herbicide use and yield comparisons with the technology.

Growers will have larger acreage blocks to evaluate the potential.

The effort has been a collaborative partnership between the Vidalia Onion Committee, University of Georgia Vidalia Onion and Vegetable Research Center, PlantTape, R and K Greenhouses, Nunhems, J.J. Broch and Bejo Seeds.

More work will need to be done, but it is a significant accomplishment to see how far the technology has advanced and to have the Vidalia industry at the forefront of the new developments.

Look for results of these plantings in future issues of Onion World.

UK Onion Pros Share Expertise S

peakers at the UK Onion and Carrot Conference, held Nov. 14, 2017, in Nottingham, reminded attendees that the future will be determined by survival of the fittest for growers. The only way to survive in the mainstream carrots and onions business is to increase yields and produce more efficiently through innovation.

Daniel Johns, deputy director of the Future Farming program at the Department for Environment, Food and Rural Affairs (DEFRA), opened the conference with reference to the future domestic agricultural policy post-Brexit.

Mike Petersen, the New Zealand special agricultural trade envoy, followed with a presentation on the impact of losing farm support in the 1980s. He summarized that change is stressful, and planning and support are required. Trade will drive innovation and prosperity. Strong farmer leadership is vital, but finally, there is no appetite in New Zealand to go back

to a farm support system. Reforms in agriculture have delivered efficiency and innovation. Strong growth in the horticulture sector continues; thus, there should be plenty of opportunity in the UK. Jonathan Gill from Harper Adams University then presented on managing the world’s first hands-free hectare. The technology used will be adapted for use in horticultural crops.

Later, the conference delegates split into two groups for separate carrot and onion technical sessions. The onion session addressed diagnostic tests from Philip Langley, an agronomist at Sandfields Farms. Dr. John Clarkson at Warwick Crop Centre presented current research on Fusarium. This was followed by a talk on selective weeding technology by Dr. Petra Bosilj with the University of Lincoln.

To conclude the session, British Onions Chairman Andrew Holding presented the prospects for the marketing season ahead.

The afternoon session commenced with agronomy opportunities for both onion and carrot crops with Andrew Francis, farm manager at Elveden Farms Ltd., sharing insight into some aspects of the farm’s production systems. Farm managers are actively involved in many research projects and encourage staff to “have a go” at new methods.

Kevin Hancock, the senior buying manager of Ocado, explained the company’s unique format for online retailing. Over the next five years, online sales will be the fastest growing channel in the UK grocery market, he said. Ocado is the second largest online grocer and continues to gain market share. The company continues to innovate to improve its customer proposition.

Tim O’Malley from Nationwide Produce gave insight into the foodservice and wholesale markets, both important customers for onions and carrots.

Sprayer Earns Award for Innovation

John Deere’s ExactApply Nozzle Control System has received the AE50 Award for 2018 from the American Society of Agricultural and Biological Engineers. The award highlights innovative designs in product engineering in the food and agriculture industries.

Introduced in 2016, the ExactApply Nozzle Control system provides improved coverage and control of spray applications with its Pulse Width Modulation (30 hertz pulsing) and automatic A/B nozzle switching from the sprayer cab. The system also offers turn compensation, individual nozzle on/off control, LED lights in each nozzle body for improved visibility, and smart diagnostics to improve, monitor and document sprayer applications at the nozzle.

According to John Deere, ExactApply enhances existing technology currently in the market and combines it into one product completely integrated into John Deere R-Series Sprayers and rate control systems.

CVS Rolls out Electric Utility Truck

Central Valley Supply (CVS) has introduced a 100 percent electric utility truck.

The Yosemite by airEoso Motor Corporation is billed as durable and rugged and built to offer strength, reliability and cost savings. It runs on standard car batteries, plugs into a 110-volt outlet, and requires no fuel and minimal maintenance. Operating costs are 75 percent less than that of a typical gas-powered utility truck, according to CVS. One-ton and half-ton models with purpose-based customizable beds, 1,500-pound towing capacity and optional four-wheel drive are available. The roll-resistant suspension and disc brakes are said to provide nimble and sure-footed handling on the road and in the field. Yosemite’s high-torque electric motor provides a minimum 80-mile or eight-hour battery life.
