OMRI-listed product from Huma controls both above- and below-ground pests
Gilbert, Ariz., U.S., July 7, 2026 – Huma® introduces PROUD 4™, a four-in-one nematicide, miticide, fungicide and insecticide, for broad-spectrum control of above- and below-ground pests. PROUD 4 is a strengthened formulation of Huma’s PROUD 3, a popular foliar pest treatment. Now growers can utilize the next-generation crop protector to also control nematodes and soil-borne diseases.
“PROUD 4 delivers best-in-class versatility and performance that can be applied any time during the year, including in-season,” says Fred Nichols, Chief Sales & Marketing Officer at Huma. “The level of control we’re seeing, along with an attractive price point, provides an unbeatable value for growers that’s OMRI-listed and safe for crops. Plus, ag retailers and farmers can stock just one product for multiple pest control needs.”
PROUD 4 is applied as a percentage of total spray solution, ranging from 0.5% to 2%. Growers can fine-tune application rates and timings depending on the species and prevalence of pests. Third-party testing shows PROUD 4 delivered excellent control of multiple nematode species – including root-knot, lesion and lance – at the lowest labeled rate. At higher labeled rates, it achieved complete inhibition of these nematodes.
“For specialty crop growers seeking alternatives to costly, environmentally harmful fumigants and synthetic nematicides, PROUD 4 is the eco-friendly alternative – eco as in both economic and ecological,” Nichols explains. “Similarly, Midwest corn and soybean growers can use it as a highly cost-effective foliar spray to control soft-bodied insects such as aphids, thrips, whiteflies, mites, and leafhoppers, as well as most fungal diseases.”
PROUD 4 provides fast-acting pest control on contact and is locally systemic. The secret sauce, explains Nichols, is Huma’s exclusive Micro-Carbon Technology (MCT).
“Carbon-rich MCT is the most efficient way to deliver crop inputs, including crop protection products,” Nichols says. “MCT speeds and enhances uptake of active ingredients, ensuring they reach their target in both the soil and leaves.”
PROUD 4 is safe to humans, plants, wildlife and the environment when used as directed. There’s a zero-day preharvest interval and zero re-entry restrictions.
