Valent BioSciences, which specializes in research and development of biological products, signed an agreement to purchase the remaining 75 percent of Pace that it didn't own, according to a news release.
Valent BioSciences already owned a 25 percent share.
Pace, which has operations in the United States, Mexico and South America, specializes in coatings, sanitizers and post-harvest disease-management products for many crops, including citrus, stone fruit, pome fruit and potatoes.
The acquisition is the latest in a move by Valent BioSciences to boost its presence in the biorational market. It currently is building a $150 million biorational product manufacturing facility in Osage, Iowa.
Biorational pesticides, which include insecticides, fungicides and herbicides, are products derived from biological organisms.
Only a day earlier on Dec. 18, Sumitomo Chemical Co., Valent BioSciences' Tokyo, Japan-based parent company, announced it planned to aquire a majority stake in McLaughlin Gormley King Co. of Minneapolis.
Sumitomo plans to increase its holdings to 76.36 percent from 32.88 percent, according to a news release.
MGK, as the company is called, sells insecticides for consumer home and pet products, professional pest control, animal health and other markets.
