Catching up with Vive Crop Protection—advanced insecticide formulations, marketing in the US, and more

Leave a reply

Starting with the “and more” part of the headline, it’s great to have found an article describing Vive Crop’s technology in language I can understand, Sadly, I failed to see it until Dec. 26, 2013,. Titled “Vive La Crop! nanotech venture vive crop protection of toronto has developed a more eco-friendly way to keep pests, fungi and weeds out of farmers’ fields. and that’s just the beginning,” is written by Tyler Hamilton for the April 2012 issue of ACCN the Canadian Chemical News (L’Actualite chemique canadienne) and it answers many of the questions I’ve had about Vive Crop’s Allosperse technology,

Pesticides don’t have the best reputation when it comes to their potential impacts on human health, but even more concerning — for regulators especially — are the volatile organic solvents frequently relied on to deliver crop-protection chemicals to farmers’ fields.

The solvents themselves are often known carcinogens, not the kind of thing we want on farmland that grows soy, corn and wheat. And they’re not as effective as they could be. Farmers tend to overspray to make sure enough of the active ingredients in insecticides, fungicides and herbicides are dispersed across a field to be effective.

It’s why Vive Crop Protection, a Toronto-based nanotechnology company specializing in crop protection, has been attracting so much attention from some of the world’s biggest chemical companies. Vive Crop (formerly Vive Nano, and before that Northern Nanotechnologies) has done away with the need for volatile organic solvents.

…

At the heart of Vive Crop’s technology are polymer particles the company has trademarked under the name Allosperse, which measure less than 10 nanometres in size. It describes these particles as ultra- small cages — or “really tiny little FEDEX boxes” in the words of CEO [Chief Executive Officer] Keith Thomas — which hold active pesticide ingredients and are engineered to disperse evenly in water.

Even and thorough dispersal is critical. Avinash Bhaskar, an analyst at research firm Frost & Sullivan who has followed Vive Crop closely, says one of the biggest problems with pesticides is they tend to agglomerate, resulting in uneven, clustery distribution on fields. “You want uniform distribution on the soil,” Bhaskar says. “Vive Crop’s technology prevents agglomeration and this is a key differentiator in the market.”

How Vive Crop chemically engineers these Allosperse particles is the company’s core innovation. It starts by dissolving negatively charged polymers in water. The like charges repel so the polymers spread out in the solution. Then positively charged ions are added to the mix. These ions neutralize the charge around the polymers, causing the polymers to collapse around the ions and create a kind of nanocage — the Allosperse.

The company then filters out the positive and negative ions and loads up the empty cages with molecules of active pesticide ingredients. The cage itself is amphiphilic, meaning it has both water-attracting and water-repelling areas. In this case, the outer shell attracts water and the inner core doesn’t. “While in water the active ingredient, which also hates water, stays inside (the cages),” explains Vive Crop chief technology officer Darren Anderson. Because the outside of the cages like water, the particles freely and evenly disperse. “Once sprayed on the crop, the water droplets evaporate and the active ingredient gradually disperses from the particles that are left behind.” How does Vive Crop assure that the Allosperse cages are amphiphilic? “I can’t tell you the answer,” says Anderson. “It’s part of our secret sauce.”

What the company can say is that the polymer cages themselves are benign. Vive Crop makes them out of chitosans, found naturally in the shells of shrimp and other crustaceans, and polyacrylic acid, the super-absorbent material found in baby diapers.

Interestingly, the core technology appears to be based on a former student project,

The core technology was developed in the early 2000s by Jordan Dinglasan, a chemistry student from the Philippines who took up graduate studies at the University of Toronto. Dinglasan and fellow researchers at U of T’s Department of Chemistry, including Anderson and chemistry professor Cynthia Goh, decided in 2006 that they wanted to reach beyond the walls of academia and create a company to commercialize the technology.

At the time of the Hamilton article, the company had 30 employees. Since the April 2012 article, the company has been busy as I’ve written an Aug. 7, 2013 posting about the US Environmental Protection Agency’s (EPA) approval of Vive Crop’s VCP-01, Bifenthrin 10 DF insecticide for foliar use on crops, turf, and ornamentals. and a September 25, 2013 posting about funding for two Vive Crop projects from Sustainable Development Technology Canada.

Now in the last weeks of December 2013 Vive Crop has issued two more news releases. First, there’s the Dec. 17, 2013 Vive Crop news release announcing a marketing initiative with a US company, AMVAC Chemical Corporation, which is wholly owned by American Vanguard Corporation and is based in California,,

Vive Crop Protection, Inc. and AMVAC Chemical Corporation are pleased to announce a collaboration to develop and market an advanced insecticide formulation for multiple uses in the United States.  The products leverage Vive’s patented AllosperseT technology delivering enhanced agronomic performance and new application opportunities to AMVAC’s customers.

“We are quite excited about working with AMVAC to add to their portfolio of innovative products,” said Vive CEO Keith Thomas. “Vive is rapidly developing a strong pipeline of effective crop protection products for our partners and growers.”

“As part of AMVAC’s continued commitment to innovate and deliver products with the best technology available, we are very pleased to be working with and investigating this new technology from Vive” said AMVAC Eric Wintemute, CEO of AMVAC .

Vive Crop followed up with a Dec. 19, 2013 news release announcing another marketing initiative, this time with United Suppliers (based in Iowa, US),

United Suppliers, Inc. and Vive Crop Protection, Inc. are pleased to announce a collaboration to demonstrate and market advanced formulation technologies in the United States. Targeted to launch in the 2015 growing season, these technologies will leverage Vive’s patented AllosperseT delivery system to provide enhanced agronomic performance and new application opportunities to United Suppliers’ leading-edge owners and customers.

“We are quite excited about working with United Suppliers to provide innovative products to their customers,” said Vive CEO Keith Thomas. “Vive is rapidly developing a strong pipeline of effective crop protection products for our partners and growers.”

Located in Toronto, Ontario (Canada) Vive Nano, a nanotechnology company acknowledged for its leadership in nanomaterial encapsulation technology, received Frost & Sullivan’s 2010 North American award for Technology Innovation earlier this year in April. (I only found out about this last week when Frost & Sullivan distributed a news release to Nanowerk. Did I miss Vive Nano’s announcement or did they just put up a news release and hoped someone would find it?) From Vive Nano’s website press release,

Vive Nano is proud to announce that it has been selected to receive Frost & Sullivan’s 2010 North American Technology Innovation of the Year Award for its unique encapsulation technology to synthesize nanoparticles. After evaluating the field of competing technologies, Frost & Sullivan was impressed by Vive Nano’s flexible process based on the principle of polymer collapse, using basic, benign, water-based inputs. Our process is green, scalable, and inexpensive – critical characteristics for addressing big challenges in global problems like food, water, and energy efficiency.

Frost & Sullivan is a global research organization of 1,800 analysts and consultants who monitor more than 300 industries and 250,000 companies.

The news item on Nanowerk offers a little more insight into Vive Nano’s current initiatives,

Vive Nano’s current industry focus is on crop protection, with subsequent applications identified in cosmetics, consumer products, pharmaceuticals, and other industrial markets. …

Pesticide formulation is a core issue in the agri-food industry. Pesticide active ingredients for crop protection need to be uniformly spread in small amounts over a large area. Towards this end, it is ideally desired that pesticide particles should not agglomerate. Furthermore, formulations of pesticides should effectively address some key industry concerns such as higher manufacturing costs, harmful environment effects, and help deliver an active ingredient which has higher initial and residual efficacy. Among the various formulation techniques, encapsulation, in which the active ingredient is encapsulated by a synthetic or biological polymer to allow for prolonged release of the pesticide over a period of time, has gained prominence in recent years due to the long term advantages it offers.

You can view a silent and text-free animation of Vive Nano’s encapsulation technology here.

I found this description from the news item helpful in understanding the technology that the animation demonstrates,

One of the key attributes of Vive Nano’s technology is that the charged polymer surrounding the core repels other “like charged” polymers thereby preventing agglomeration and helps maintain the nano size of the particle. “Vive Nano’s technology offers some key advantages such as its ability to create nano particles for most chemicals on the periodic table and high scalability in manufacturing that allow it to scale to thousands of tons,” says Frost & Sullivan Research Analyst Avinash Bhaskar. “Further, the technology does not need a dedicated plant and is easy and cost-effective to implement.”

Vive Nano’s initial testing has successfully demonstrated that its nano technology-based formulated active ingredient is highly effective for killing weeds while avoiding the problematic chemical additives that are leading to product bans in a growing number of major markets. Vive Nano’s nanoparticles have the potential to result in improved crop yield and reduced environmental impact.

Congratulations Vive Nano!
