Field tests were conducted in Missouri and South Carolina to evaluate uniform and random plant stand reductions in cotton rows.  Treatments were applied to simulate 50 to 90% plant reductions by hail storm at early square.  Uniform reduction were made by blending conventional (non-glyphosate resistant) and glyphosate resistant seeds and spraying with glyphosate.   Random stand reductions were acheived by hand thinning based on a random number generator. For comparisons, even stands were planted with normal and low seeding rates.
