14 14 Chemigation Applications Drip irrigation Solid set sprinklers Module 2: Soil Fumigant Uses

15 15 Other Application Methods Tree hole Hot gas Rotor tiller Module 2: Soil Fumigant Uses Spray blade

16 16 Review Questions True or False? 1. Fumigation of soil for potatoes is a major use. 2. Fumigant usage across the country is similar. 3. Application methods differ by chemical.

17 17 Summary  Use of soil fumigants on major food crops ranges from about 2 to 45.5 million pounds per year  Largest use on potatoes, strawberries, tomatoes & carrots Data lacking for nursery uses  Amounts used vary by chemical, application method & geographic location Module 2: Soil Fumigant Uses
