Get ready for the future of agricultural pest control

The name “pest,” which at times means “nuisance” or “annoying,” doesn’t do the best job at portraying the devastating nature of the insects who attack crops and agriculture around the world.

Some estimates provided by academia show us that insects can destroy up to 10% of crops in developed nations; in nations that are still developing, pests can take up to 25% of the food being grown. Reports out of Ghana indicate that pests and diseases claim up to 30% of that country’s crops.

In America, this year has seen a number of troubling insect infestations which have led to major issues in agriculture. An Oriental fruit fly infestation in Florida has led to quarantines affecting up to 500,000 pounds of mamey and 20 million pounds of dragon fruit that would otherwise be harvested.

Over in Arkansas, local agriculture experts have issued an alert for unusually levels of earworms, stink bugs and other pests that affect soybean and rice grown in that state. Arkansas is further suffering from new infestations by two insects, the kudzu bug and the sugarcane aphid, which entered the state in 2014 and could attack grain sorghum and more soybean.

Pesticide regulation in the US goes back to the 1950s when two amendments were made to the Federal Food, Drug and Cosmetic Act. The Pesticides Control Amendment of 1954 gave the Food and Drug Administration (FDA) the ability to ban pesticides which it found to be unsafe.

In 1958, the Food Additives Amendment introduced the Delaney Clause which contained strong provisions against pesticides found to cause cancer in animals. A few federal agencies provide surveillance of pesticide use in agriculture, including the U.S. Environmental Protection Agency (EPA).

The EPA promotes the Integrated Pest Management program, which seeks the judicious use of pesticide supported by other pest reduction techniques, including crop rotation or planting pest-free rootstock. The U.S. Department of Agriculture (USDA) administers the Pesticide Data Program, which collects data for producing a database of pesticide residues found in American crops.

In 2014, about half of the food tested by the USDA showed signs of pesticide residue, although most were within levels recognized as safe by the U.S. government.

So there remains a need to address insect and pest problems popping up across the country and pesticides can only be one component of the solution. Today, we’ll be exploring the agricultural world to see what kind of answers have been developed in order to protect crops while ensuring the production of food which is safe for human production.

As is the case for just about every other industry across the world, the Internet of Things has been lauded as a potential boon for crop production, including pest control. Vancouver-based tech company Semios offers an integrated pest management program which utilizes a network of camera-traps to provide farmers with automated pest counts and pest pressure notifications.

The Semios system also enables the dispensing of pheromones which can disrupt typical mating schedules for some pests.

Automated IoT pest control systems have also been developed by Spensa of West Lafayette, IN. Its Z-Trap unit is specifically designed for apple orchards to detect the levels of codling moths, one of the more common North American pests for apple trees.

Spensa’s Z-Traps can be monitored remotely with the MyTraps software application that the company has developed to record and visualize pest populations from a computer, Android or iPhone. This technology is also being developed to detect for Oriental fruit flies and obliquebanded leafrollers. Pest monitoring systems such as this enable farmers to more effectively apply pesticides and hopefully reduce the amount of pesticide used on plants.

Biopesticides are an area of pest control tech which utilize natural, non-synthetic materials that have pesticidal characteristics. The EPA recognizes three different kinds of biopesticide: microbial pesticides, which utilize bacterial or fungal microorganisms; plant-incorporated-protectants (PIPs), genetic material with pesticidal characteristics which can be incorporated into a plant; and biochemical pesticides, naturally occurring substances which can kill pests through non-toxic mechanisms.

Microbial pesticides for use as agricultural biopesticides are an R&D focus for Marrone Bio Innovations Inc. of Davis, CA. On September 14th, the company announced that governmental agencies in Europe gave approval for the company’s Grandevo bioinsecticide to be evaluated as a microbial pesticide, the first such microbial pesticide to be evaluated by EU agencies which doesn’t contain live microbes.

Grandevo is developed as a broad-spectrum biopesticide that works against chewing and sucking insects like mites, armyworms and soil-inhabiting pests. The company also markets a biofungicide known as Regalia, which is applied to plants to induce a defense response which both inhibit fungal growth and improves plant vigor.
