Abstract
An agricultural bactericide series is prepared from hymexazol [chemical name: (3-hydroxy-5-methyl isoxazole, see structural formula(I)], metalaxyl (DL-N-(2,6-dimethyl benzene)-N-(2-methoxyacetyl) amino methyl propionate, see structural formula (II), organic acid and assistant through proportional mixing. Its advantages are low poison, broad spectrum and high effect to several diseases such as rice blast, damping-off frosty mildew, etc..
Description
＜one〉technical field
The present invention is that the hymexazol powder that utilizes this school new technology (number of patent application 99115140.2) to produce is the mould clever concentration height of evil of primary raw material preparation, and sterilizing ability is disliked the strong and one group of wider disinfectant use in agriculture of bactericidal range of mould spirit than using separately.
＜two〉background technology
One group of disinfectant use in agriculture of the present invention's preparation, we are referred to as 5% organic acid and dislike mould first frost aqua (former %5 Hymexazol-matulaxyl aqua alleged in first to file 99115140.2), be that we screen the prescription that draws through chemical agent screening and field experiment, at home and abroad do not appear in the newspapers.
The object of the present invention is to provide a kind of efficient, low toxicity and than disliking the more bactericide of wide spectrum of mould spirit.Rice blast is had special efficacy, and to sickle-like bacteria, the control of various crop damping off, damping off, banded sclerotial blight and downy mildew that silk capsule Pseudomonas, corticium cause has special efficacy.
