Griffin L.L.C. announces good news for walnut growers. Manex fungicide can be added to their disease management program.
Manex is excellent for controlling copper-tolerant walnut bacterial blight. A Section 18 emergency exemption was recently issued by the California Environmental Protection Agency (CAL-EPA) for the use of Manex between March 1 and June 15, 2001.
This exemption is valid in the California counties of: Butte, Calaveras, Colusa, Glenn, Merced, Placer, Sacramento, San Benito, San Joaquin, Santa Clara, Shasta, Solano, Stanislaus, Sutter, Tehama, Yolo and Yuba.
“Manex is the ideal tank-mix partner. It has proven crop safety, is non-phytotoxic and won't increase spray burn,” says Bob Higby, regional sales manger for Griffin. “Manex has excellent synergistic activity with copper fungicides, such as Kocide, and can play a vital role in controlling copper tolerant bacteria when used in a tank-mix combination.”
For best results, apply Manex at 1.8 quarts per acre as a tank-mix with Kocide 2000, Kocide DF, Kocide LF, or Kocide 101 at every blight spray.
Start applications at early bloom — prior to or when catkins are partially expanded — and continue at weekly intervals during periods of rainy, moist weather. A Manex tank-mix can be applied by air or ground equipment. Growers should not exceed 10 applications per season.
Application to walnuts must be conducted with the California Section 18 Emergency Exemption labeling in hand. Contact your county agricultural commissioner for instructions prior to application.
