As a type of pesticide, biopesticides, of course, are supposed to kill bugs, or, preferably, keep them off crops, by using natural, organic methods, instead of chemicals. However, the field is relatively new, and as of now there are no biopesticides strong enough to handle the entire growth cycle. There are various technologies to produce biopesticides, such as using plant extracts to develop organic chemicals that can be applied to plants and crops, along with microbial biopesticides based on using bacteria, fungi and yeast extracted from plants (Stockton uses both, said Ziv Tirosh, CEO of Israel’s Stockton Group).

Though promising, wide-scale, cost-effective production of genetically engineered biopesticides is years away. “A lot more research is needed, and the small start-ups that generally work on these projects don’t have the money or resources needed,” he said. The infrastructure – from the marketing and sales channels to the methods of application – is all geared towards chemical pesticide treatment, so replacing it is a non-starter.

However, Tirosh said, biopesticides can – and already do, thanks to Stockton – play a crucial role in assisting chemicals do a better job. “If, for example, a cucumber crop will be sprayed ten times, we could replace two or three of those chemical pesticide sprayings with biopesticide sprayings that will have an important impact on the final results.”

Timorex, Stockton’s main product, has been feted not only by the EU, but by industry as well. The company won this year’s Agrow Award (given out by agriculture industry information giant Informa Agra) for the best new biopesticide.

One clear use case for biopesticides, he said, was towards the end of the growth cycle. When a fruit or vegetable is sprayed with chemical pesticide, some of it is absorbed, but most of it washes away. “Growers are reluctant to use chemicals at that point because they don’t want any residue when they being the crops to market,” Tirosh said. At that point, many farmers prefer an organic solution – like Stockton’s biopesticides – which, if not as effective as chemicals, are still quite effective, and do the job of protecting crops as they make their way to the dinner plate, with fewer chemicals.“The statistics on population growth and the need for more food are well known,” he said, pointing to studies that say there will be as many as 8 billion people in the world within 25 years. “Chemical pesticides are by far the most effective way of keeping infestations out of crops and ensuring that there is enough production to feed the world.” As such, he said, biopesticides will not replace chemical pesticides anytime soon. “They just cannot be used as effectively, cheaply, and on as large a scale as chemicals. But in a supporting role, biopesticides can greatly enhance agriculture.”

“There are use cases for using biopesticides in other parts of the growth process as well,” Tirosh said – for example, replacing one or two of the chemical sprayings just to keep bugs from having access to them and building up a resistance. Thanks to biopesticides, chemical pesticides can have a longer, more effective life cycle in agriculture.

Combining the powers of biological agents and synthetic chemistries

As a leader in biopesticides innovation, STK Bio-ag Technologies (formerly Stockton) is pioneering a new generation of ‘hybrid pest control’ products that combine the powers of biological agents and synthetic chemistries, and which may present a new era in pest control. With recent partnership agreements with industry giants such as BASF, Syngenta and Seipasa, this seemed like a great time for Chemicals Knowledge to catch up with STK’s Chief Scientist, Professor Moshe Reuveni. STK seems to be in a great place right now! How have the values and mission of the company led you here? STK was founded and is headquartered in Israel, the ‘innovation nation’! Innovation and sustainable agriculture are in our DNA, and we are committed to the values of sustainable agriculture – from field to fork. This stems from our main mission to provide premium, highly effective products, with low chemical residues and novel and unique mechanisms of action (MOA). We also aim to provide additional yield benefits, and to ensure that our products are flexible and easy to apply, and chemically compatible with many other active ingredients. What are the main benefits of biopesticides? There are many advantages. Biopesticides come from nature – they may be plant extracts, like Timorex Gold, which effectively ruptures pathogen cells (Figure 1), or bacteriological, like Aviv, a powerful Bacillus subtilis requiring less than half the dosage of other biopesticides. In any case, biopesticides contain no synthetic chemicals. They are produced from renewable sources, and they leave minimal crop residue, making crops treated with biopesticides much more competitive in domestic and international markets. Regulators, consumers and retail supermarkets all want to reduce the chemical residue on their produce. The selectivity of biopesticides, which target only their natural enemies, also helps to maintain beneficial insect and mite populations, ensure worker safety and promote environmental safety. Today’s biopesticides are as effective – or even more effective – than synthetic chemical pesticides, in terms of crop protection and increasing yields. Furthermore, biopesticides are an important weapon in managing pesticide resistance. They can help reduce the selection pressure for the evolution of resistance to synthetic pesticides, and the risk of pests and pathogens developing resistance to biopesticides is low, especially as these agents often have multiple modes of action. Switzerland recently announced that it is considering a total ban of synthetic pesticides – do you think it is feasible to have a world free of synthetics? The world’s population is expected to grow from the current 7 billion people to 9 billion people by 2050. In order to feed all of these people and avoid mass starvation, mankind will need to double crop yields globally. This is a tall order, and to achieve this, growers will need effective tools for combating diseases – we think this will need to include biopesticides and synthetic chemical pesticides; or hybrid technologies that combine the two. The use of biopesticides is forecast to grow by 15% to 20% annually for the foreseeable future, while synthetic chemical use is predicted to grow at a slower annual rate of 3%. If those growth rates are maintained, eventually we will be in a situation where more biopesticides than synthetic pesticides are being used. We think this will be a good situation to be in, for the many reasons discussed above, but we still see a continued need for good synthetic pesticides. Can you tell us more about ‘hybrid’ technologies and how they expect to encourage uptake of biological agents? STK has introduced the world’s first ‘hybrid’ pesticide, Regev – the ‘pre-mix’ of a synthetic pesticide with a botanical-based biopesticide. Specifically, it combined a Tea Tree botanical extract and difenoconazole in an easy-to-use formulation. The combination of a natural product with broad-spectrum activity and a traditional site-specific synthetic provides growers with the different modes of action of a botanical-based active ingredient and an effective chemical pesticide. The hybrid combination results in a reduced synthetic chemical load on the environment, compared with other traditional mixtures based on two synthetic chemicals. Regev is an effective and unique tool for resistance management, and it is clearly suitable for Integrated Pest Management (IPM) programs. This product is also a bridge for growers who have never previously tried a biopesticide. These growers can use Regev in exactly the same way as their current chemical pesticide: no mixing, no rotating, easy-to-use… and with the benefits of lowering chemical residues, improved resistance management and yield growth. Regev will accelerate the uptake of biological products by making it easy. Historically, biopesticides have been used largely on high-value crops, such as fruits and vegetables, but hybrids like Regev are not only being used on fruits and vegetables, but have proven to be a cost-effective approach for row crops like soy beans, and field and broad acre crops like corn. Regev is already being used in 10 countries throughout Latin America, Israel, Serbia and the Philippines. Plans for 2019 call for the global rollout of REGEV. How are you working with global majors to encourage global distribution of these technologies? To accelerate the distribution of STK’s biological technologies for sustainable agriculture, we have entered into partnerships with various companies . In Brazil, Timorex Gold botanical-based biofungicide is co-distributed by both STK and BASF, which is proving to be very effective in this very large country. In the US, Aviv, our low-dose Bacillus subtilis biofungicide, is distributed by Syngenta. Not all of our distributors are the global majors, and STK is always open to partnerships with companies large, medium and small. What’s next for STK? Beyond the continuing geographic distribution of Timorex Gold, Regev and Aviv, STK has a powerful pipeline of new biological products to provide new tools to help growers reach the goal of doubling their yields by 2050. This pipeline includes new biopesticides based either on powerful natural plant molecules or plant extracts to be used as bio-fungicides or bio-insecticides. In addition, new hybrids combining natural active ingredients and reliable synthetic active chemicals, to be used on wide range of crops and pathogens, are under development.

STK Welcomes French Wine Growers to Israel for Sustainable Solutions

December 31,  2018  (Petach Tikvah, Israel) – STK bio-ag technologies, the innovative Israel – based leader in bio-ag technology for sustainable crop protection and aquaculture, hosted a group of 13 top wine growers and crop protection experts from France who are learning about botanical-based and  hybrid technologies for sustainable grape growing for the creation of high quality French wines, champagnes and cognacs. Effective September 1, 2018 all Neonicontinoid pesticides have been banned from use in France, because they are believed to be killing the bee population. New French law also makes it illegal to use any chemical pesticide in any park or public place after 2020, punishable by a 30,000 Euro fine and 6 months in jail.  According to the Telegraph (Henry Samuel, August 31, 2018, Paris), France is the first country in Europe to ban all five pesticides researchers believe are killing off the insects. Consequently, wine growers in France are in search of new tools for sustainable crop protection. STK VP R&D and business development Shay Shanan commented, “STK is happy to have welcomed these top French wine growers and crop protection experts.  STK’s botanical-based biopesticides and hybrid products are currently providing sustainable solutions for growers in over 30 countries, and there is no doubt these technologies can help growers in France to comply with the new regulatory environment and continue to provide their customers with the highest quality wines,  with less  chemical residues. For new users of biological products, Timorex Gold and REGEV are highly recommended, especially for wine grapes, for the control of Botrytis and Powdery Mildew.  REGEV is  a new hybrid product with a very easy approach, applied in exactly the same way as the growers’ current chemical pesticides, with no mixing, resulting in much lower residue levels and much better resistance management .”
