Tank Mixing Pesticides for Crop Production or Vegetable Management

Before you mix products, make sure that each product is registered for the intended use. Always check the product labels for the recommended crops, pests, rates, timing and adjuvants and follow all the label directions on each product used in the tank mix. Make sure that you:

· use an adjuvant only when directed by one of the labels
· apply at the recommended growth stage of the pests and crops on each label and that these are compatible
· follow the directions on the label that best protects you and the environment, such as using the largest buffer zone, longest re-entry and pre-harvest intervals and wearing the most protective clothing and personal protective equipment
· don’t mix pesticides if one of the labels states not to mix them

If you mix pesticides that do not have tank mixing directions on one of the labels, there is no guarantee that the tank mix will work. Severe problems could result, including:

· increased hazards to you, the applicator.
· a chemical reaction occurring between the pesticides. The toxicity of the mixture may be reduced or it may increase.
· reduced pest control. This is called an antagonistic reaction.
· unacceptable residues on the crop.

When compatible products are tank mixed, the effectiveness of the mixture could be greater than either of the products alone. This is called a synergistic reaction.

If you mix products that do not have tank mixing directions, you are responsible for what happens. If unsafe conditions result from using the mix, you may be prosecuted under the Pest Control Products Act.

Before you mix products, make sure they are physically compatible. Test them by mixing a sample ahead of time. Do not experiment with an untested tank mix on the day of application. Pesticides are considered compatible if they mix well in the spray tank and work effectively together. Do not use pesticides together if you see separation, coagulation, gelling or curdling when they are mixed. These pesticides are not compatible. Mixing two pesticides which are incompatible is costly and time consuming. Check the label for information about compatible products.

Restricted Entry Intervals

Restricted Entry Interval (REI) is the period of time after a pesticide has been applied that agricultural workers or anyone else must not do hand labour tasks in treated areas. The REI allows the pesticide residues and vapours to dissipate to safe levels for work to be done. Hand labour tasks involve substantial worker contact with treated surfaces such as plants, plant parts or soil. Examples of these activities include: · harvesting, detasseling, thinning, weeding, scouting, planting, mowing, roguing, and packing produce into containers in the field or greenhouse. You can only do these tasks after the Restricted Entry Interval has ended.

Water Soluble Packages

Water Soluble Packages (WSP) are designed to reduce exposure during mixing and loading. However, the Agricultural Handlers Exposure Task Force (AHETF) found that ► users were more exposed when using Water Soluble Packages than Wettable Powders. Exposure occurred when users sprayed high pressure water on the packets and/or intentionally broke the packets to help them dissolve. Use Water Soluble Packages properly to reduce exposure. Follow these handling and mixing instructions developed by the United States Environmental Protection Agency and the AHETF. Handling Instructions • Mix in the spray tank only. • Keep the WSP intact. Do not cut or puncture the WSP. Do not break or release the contents. • Keep the WSP in the outer packaging until just before use. • Keep the WSP dry until adding it to the spray tank. • Reseal the WSP in its outer packaging to protect any unused WSP(S). • Handle with dry gloves. If the WSP tears or ruptures before or
