Thirteen weekly applications of Evisect 50SP or Ekalux 480E at 0.5, 1.0 and 2.0 lb (AI)/100 gal were compared to 13 weekly applications of Trigard at 0.125 lb (AI)/acre. The materials were applied to 27 cultivars of chrysanthemums grown under commercial conditions without cover by the cooperating grower (San Luis Rey, CA). The plants were planted 6 Aug; treatments were initiated 13 Aug and ended 5 Nov. Six plants of each variety were planted in each of 7 rows, with 1 pesticide treatment per row. The materials were applied with a 15L backpack sprayer.
