The present invention discloses an infective
rhizoctonia disease compound bactericide and a production method of the bactericide, which consists of a bactericide and an acid regulating agent; wherein, the effective compositions of the bactericide consists of the
thiram, the
metalaxyl, the
ziram and a carrier; the acid regulating agent consists of the
sulfuric acid and a carrier. The production method of the present invention is to uniformly mix the raw materials such as the
thiram, the
metalaxyl and the
ziram with the carrier to be made into a single-bag product of the bactericide; to spray the
sulfuric acid on the carrier and to re-mix to be a carrier containing the acid, thereby producing an acid regulating sing-bag product. Re-mixing the
thiram, the
metalaxyl and the
ziram, the present invention has a favorable combinational
toxicity, which can improve and protect the growth environment of the crops and can prevent the occurrence of the
zinc deficiency. The compound bactericide is made by the
powder acid regulating agent directly mixed with the soil, which is simple and convenient to operate; the effective composition of the compound bactericide can increase the
seedling in the tri-leaf period to ten or more; the present invention adopts the
coal gangue powder and the rice
hull powder as the acid carrier, which has high content of the acid and has a favorable
aeration; moreover, the
coal gangue powder is an organic substance, which can improve the soil without any
pollution. The efficiency for adopting the present invention to prevent the rice infective
rhizoctonia disease can reach ninety nine percent or more.
