TIPS ON TANK MIXING |
|
| Tank mixing
chemicals can accomplish broad spectrum pest control and can reduce labor costs at the
same time. As very few manufacturers will state which competitive products are compatible
with their own, the end user must rely on their own experimentation and test different
combinations to determine compatibility and potential phytotoxicity. There are several rules to follow when tank mixing to avoid incompatibility and phytotoxicity. The physical nature of a pesticide is more important than its chemical nature in determining compatibility, although that information can be valuable. All pesticides are divided into three chemical classes: Nonionic (no charges); Cationic (positive charges); and Anionic (negative charges). Surfactants are often "nonionic". Most insecticides are produced as oil-soluble concentrates to which emulsifiers have been added to make them emulsifiable in water. Never mix two E.C.s (emulsifiable concentrates) together. Read the labels carefully for all products you plan to tank mix. Never apply more than the label recommended rate. Do a "jar test" for compatibility before you tank mix pesticides in your sprayer. 1) Add one pint of water (or carrier) to a quart jar. Add each pesticide, one at a time, shaking well after each addition. Use each product in the same proportion to water (carrier) as it will be in the actual tank mix. Repeat this process in a second jar but add an adjuvant to the water then add the pesticides. A mixture may fail without it, but be compatible when an adjuvant is added. |
2) Unless
the label states otherwise, add the pesticides in "W-A-L-E" order:
