Here’s how New Zealand is helping spread smart pest management

OPINION: The world’s population is projected to reach 9.8 billion by 2050, which means an extra two billion mouths to feed.

The limited resources we have on the planet need to be utilised sustainably to maximise the quality and quantity of food.

To achieve this, smart integrated disease and pest management (IDPM) will be key because crop disease epidemics can severely disrupt food supply.

At the other end of the spectrum, some growers may feel economic pressure to switch to organic practices in order to meet consumer demand, even though biological and cultural control methods alone are sometimes insufficient in controlling pests and diseases.

Organic produce has become increasingly popular in recent years, and is often perceived as a more “sustainable” alternative. The paradox here is that some organic orchards also use copper-based fungicides, despite copper potentially having a lasting impact on soil.

Growing conditions are never static. Given optimal conditions, diseases can spread like wildfire in a very short period of time, even in areas that normally produce healthy crops. In conditions favourable for a particular fungus, fungicides are important tools for the management of epidemics.

In Europe, for example, yellow rust (Puccinia striiformis) has expanded further across the continent in recent years and the application of fungicides has avoided major yield losses in wheat. Potato late blight (Phytophthora infestans), which was responsible for the Irish potato famine of the 19th century, still presents problems for potato growers worldwide. Severe outbreaks in some areas of Germany, caused by humid weather, have hit organic farmers especially hard in recent years.

Another example is coffee leaf rust (Hemileia vastatrix), which has caused annual yield losses of 30 per cent or more in some regions of Latin America over the last decade. This led to the use of integrated management strategies, including fungicide spraying based on disease monitoring, the introduction of new, resistant varieties and better nutrition of the crop.

IDPM consists of three components: biological (controlling diseases and pests using other living organisms), cultural (crop rotation, appropriate varieties, removing infected material) and chemical (the use of pesticides following pest and disease monitoring). IDPM guides growers to find a balance between these different components, including the safe and responsible use of chemical products when needed.

Plant & Food Research, with the support of the New Zealand Aid Programme, has been working with agronomists and growers in countries such as Cambodia and Vietnam to incorporate IDPM practices into their production systems.

This has already seen promising results in combating local fruit and vegetable diseases by improving orchard design and hygiene, and optimising spray programmes. If smart IDPM systems are further established in these countries, growers will be able to produce crops more efficiently and responsibly.

This will also reduce exposure to health risks associated with the misapplication of chemical products, as well as sparing beneficial organisms already present in orchards that act as a biological control.

Although New Zealand growers already follow integrated management practices, scientists are continuously investigating how these can be adapted to changing environmental conditions and agricultural production processes. For example, a range of on-orchard factors can impact avocado fruit quality. At Plant & Food Research, we are currently working with the avocado industry to better understand fruit quality and help growers improve fruit quality outcomes from their orchards.

Some recommendations from previous research on insect pests have already been successfully implemented, and the New Zealand avocado industry has a well-recognised integrated pest management strategy.

I believe science that develops smart IDPM practices today will help to resolve a potential food crisis tomorrow. IDPM has the potential to maximise food productivity and quality worldwide, while maintaining a sustainable equilibrium between disease and pest management, environmental conservation, the needs of growers, and consumer benefits.

Integrated pest management gains momentum due to European regulations on pesticides reduction. But the challenges are to integrate all alternative methods and to get farmers involved.

Reducing the level of pesticide use in agriculture is a priority in Europe. A 2009 EU Directive states that the use of pesticide must be compatible with sustainable development. In particular, it encourages so-called integrated pest management (IPM) initiatives. IPM consists in combining available biological, genetic and agricultural methods to fight pests—such as weeds, bacteria, viruses, insects and fungi – rather than using extensive pesticide spraying.

Now the EU-funded PURE research project, due to be completed in 2015, aims at providing practical IPM solutions to reduce dependence on pesticides in selected major farming systems in Europe. “Our final objective is to provide farmers a toolbox for implementing IPM,” says Françoise Lescourret, director of research at the plants and cropping systems in horticulture laboratory at the French National Institute for Agricultural Research (INRA), in Avignon, France. She is also the project coordinator.

The research focuses specifically on six cropping systems: wheat and maize as field vegetables, as well as pomefruits and grapevine as perennial crops, and tomato as greenhouse crop. Field tests are carried out in ten European countries. Project scientists are testing several solutions including, for example, the phasing of sowing in response to pest emergence, the use of plant species resistant or tolerant to biological aggressors, and the release of predator insect species in greenhouses.

Alongside these existing methods, the project team also evaluates innovative technological solutions, such as air samplers that can warn the arrival of airborne inoculum of pathogens, or mating disruption for insects involving the release of pheromones.

Then, IPM models taking into account experimental results are designed in the lab, and tested back in the field, in a virtuous circle. “Combining IPM solutions is challenging as all problems do not arise at the same time in farms,” Lescourret tells youris.com.

Assessing the cost of these solutions before and after implementation is also a key point of the project. “A good [integrated pest management] solution results in a positive environmental impact, a good cost-versus-benefit ratio, and preserves the social well-being of agriculture professionals,” she tells youris.com.

Economic aspects are indeed crucial. “In order to execute IPM, many more economic thresholds for pest, disease, and weed infestation are needed. Economic thresholds are the levels of the pest that will cause economic loss if the pest is not controlled. Controlling the pest below this level is wasteful, costly and a totally unjustified use of pesticides. In order to assess if a pest is above this threshold, farmers needs more sampling methods to measure the pest level. PURE can add to their toolbox” says Richard Meadow, research scientist at Bioforsk, the Norwegian Institute for Agricultural and Environmental Research, in Ås, Norway.

However, a toolbox is not enough, for Hans Muilerman, pesticides & alternatives officer with PAN Europe, the European subsidiary of pesticide action network federating environmental NGOs. “The main thing farmers need is good examples. If the ‘hero’ of the region adopts IPM, many will follow. Governments should start ‘IPM-hero’ programs and stimulate it. A toolbox is only needed when farmers feel like changing and this is the big hurdle for now,” he tells youris.com.

By the time the project reaches completion, however, the European network ENDURE for the promotion of sustainable agriculture will take over and spread the results among agricultural advisers to maximise the chance that project findings will be implemented.
