The invention provides a seed
coating agent of
waxy corn, which comprises the following components in percentage by weight: 1 to 2 percent of
polyvinyl alcohol, 3 to 8 percent of
gum arabic, 0.1 to 1percent of surfactant, 2 to 5 percent of antifreezing agent, 0.1 to 1 percent of defoaming agent, 1 to 2 percent of warning color, 0.5 to 1 percent of
thiamethoxam, 0.5 to 2 percent of
cypermethrin, 1to 2 percent of carboxin, 0.1 to 1 percent of
fludioxonil, 0.1 to 2 percent of
chitosan, 1 to 2 percent of
potassium fertilizer, and the balance of water. The seed
coating agent achieves effective control efficiency to soil insects (cutworms, grubs and the like),
stem rot, head
smut and aphids, generates obvious control efficiency to diseases and
insect damages, and has low dosage. The
germination speed of
waxy corn seeds is increased by 0.5 day, seedlings grow robustly, the dry
fresh weight is increased, and the comprehensive control efficiency of
plant diseases and
insect pests reaches 90.80 percent; and at the
harvest time, the spike length, the spike thickness and the spike
grain number are improved compared with a contrast, and the yield of the corn is improved by 10 to 15 percent.
