Description
Technical Field
The invention belongs to the technical field of pesticides, and particularly belongs to a plant growth regulator and a preparation method thereof.
Background
Paclobutrazol is a plant growth regulator, can cause the metabolism and the structural change of a plant body, inhibit the growth of a main root, promote lateral root tillering and rooting and increase the surface area of a root system; inhibiting the elongation of the stem branches to make the stems stout; can also reduce the leaf area, increase the leaf thickness, improve the contents of chlorophyll, protein and nucleic acid in the leaves, quickening the photosynthetic rate, enhancing the cold resistance and drought resistance and delaying the plant aging. At present, researches on paclobutrazol are mostly concentrated on the aspect of plant growth regulators, but researches report that paclobutrazol also has a control effect on crop bacterial diseases, and application number CN201410787905.8 discloses a compound composition and a preparation containing methanesulfonyl bacteria oxazole and a plant growth regulator, and specifically discloses that one of methanesulfonyl bacteria oxazole, brassinolide, compound sodium nitrophenolate, diethyl aminoethyl hexanoate, sodium naphthaleneacetate, triacontanol, gibberellin, forchlorfenuron, paclobutrazol, indoleacetic acid, trinexapac-ethyl, chlormequat-ethyl, prohexadione, hydroxyalkenadenine, choline chloride and 6-benzylaminopurine has a synergistic effect, and can be used for controlling crop bacterial diseases.
Carotovorum (pectobacterium carotovorum subsp. Carotovorum) can cause cabbage bacterial disease — cabbage soft rot. The soft rot of the Chinese cabbage is one of the main diseases of the Chinese cabbage, can occur in the growth period, the transportation process and the storage period of the Chinese cabbage, seriously affects the yield and the quality of the Chinese cabbage, and causes the yield reduction of the Chinese cabbage by more than 50 percent when the occurrence is serious, even never receives the disease. At present, chemical control is the main control measure of Chinese cabbage soft rot. In the growth process, although the Chinese cabbage soft rot can be prevented and treated to a certain extent by adopting a broad-spectrum medicament, the broad-spectrum medicament has poor pertinence and undesirable prevention and treatment effect. In addition, the single medicament is frequently used, so that the resistance of pathogenic bacteria is easily enhanced, the control effect of the pathogenic bacteria is reduced, the use amount is increased, the environmental pollution is caused, and the pesticide residue exceeds the standard. Therefore, the reasonable use of the pesticide and the screening of the high-efficiency and low-residue prevention and treatment agent have important significance for the production of the Chinese cabbage.
Compounding different kinds of pesticides is a common method for developing novel medicaments. The inventor finds out through experiments that the compounding of paclobutrazol and zhongshengmycin, kasugamycin or zinc thiazole shows a synergistic effect on inhibiting pectobacterium carotovorum and can provide support for preventing and controlling Chinese cabbage soft rot.
