Other applications for CaTS have included: 1) providing a source of Ca and S nutrition for cotton, 2) reducing bitter pit in apples, 3) combating blossom end rot in tomatoes, and 4) minimizing tip burn in lettuce. Magnesium thiosulfate Magnesium thiosulfate (MagThio) is the latest product in TKI's line of thiosulfate materials. It contains 4 percent magnesium and 10 percent S with a neutral to slightly basic pH. It has the same characteristics of other thiosulfates where low salt-out temperature is desirable under cool Treatment Rate/A Applications Yield tons/A Control 29.65 MagThio + Reason 1.0gal+5.5oz 2 32.71 * MagThio + Headline 1.0gal+6.0oz 2 32.70 * MagThio + Tanos 1.0gal+6.0oz 2 32.82 * Magnesium sulfate + Reason 1.0 gal + 5.5 oz 2 31.30 * * timing: first row close, second full canopy Table 2.

In field trials on potatoes, MagThio applied as a foliar spray in combination with fungicides has produced positive yield responses (Table 2). It can also be blended with KTS, liquid urea, and some UAN solutions, depending on the type of rust inhibitor they contain. Other crops on which MagThio is being tested include citrus, melons, apples, beans, and grass seed. Additional thiosulfates formulations currently being studied include zinc and manganese.
