The invention relates to granules containing trichoderma harzianum and humic acid. The granules contain the active ingredients of the trichoderma harzianum, hymexazol and the humic acid. According to the granules, trichoderma harzianum technical concentrate with the content equal to 30 billion CFU/g serves as the technical concentrate with the content equal to 100%. The granules are prepared from, by weight, 1-25 parts of the hymexazol, 1-5 parts of the trichoderma harzianum and 10-80 parts of the humic acid. According to the prepared granules, the medicament is convenient to use and is applied through broadcast application or hole application or furrow application, spraying can be conducted without water blending, the hysteresis control of water blending spraying conducted by farmers due to the fact that soil is drier is overcome, timely control over germs during peak seasons after the rain can be facilitated, and loss is reduced. By means of the active ingredients, the synergistic function on germ prevention is achieved, the use amount of each single dosage can be decreased through reasonable proportion and blending, and saving of dosage use cost is facilitated.
