Using the Bio-Ag NSI 3-prong attack helps growers to maximize their results in wine, table or raisin grapes.

Our Mission

Bio Ag Services began working with growers in 1975. Greg Gaffney the founder wanted to find a different method of controlling ag pests without using chemicals. In 1975 Greg laid the ground work at California State Fresno and with the help of renowned biocontrol professors at University of Berkeley used predatory mites to see the impact on pest mites on almond trees. The study orchard did not have to spray for mites and it was the 1st demonstration that commercially releasing predatory mites worked. 

We soon installed greenhouses to raise predatory mites for commercial release in trees and vines. Bio Ag Services was the 1st company to commercially rear and release predatory mites in California. The philosophy of Bio Ag was not to just release the predators but have a monitoring system for all pests, diseases, nutrition and cultural practices. In 1980 Bio Ag was bucking the trend at the time consulting with over 40,000 acres.. Now predators and parasites are mainstream in agriculture.

BIO-AG has been helping farmers increase their yields since 1975

Soil and Foliar Nutrients, Organic Soil Food, Fertilizers by Greg GaffneyBIO-AG president Greg Gaffney received his MS in horticulture at CSU Fresno in 1976.  His other major areas of study include soil/plant nutrition and entomology.  He started BIO-AG in Fresno, CA in 1975 and began specializing in biological control and plant nutrition.  Using his own lab for analysis, he became the first company commercially rearing and releasing predatory insects in the San Joaquin Valley.

In 1980, Greg began his own organic farming operation in Fresno County.  His first crops were mainly vegetables and fruit trees.  He started the first local composting operation using the Scarab machine.  Use of this device is now common among farmers. 

A member of California Certified Organic Farmers, he has represented this organization at the state level for two years and at the county level for four years.  During his many years as an organic farmer, his unique blends of organic materials (especially kelp-derived products) have attracted considerable attention in the farming industry. In addition to selling these products to farmers, Greg is available as a soil and plant nutrition consultant and welcomes your farming questions.
