Moisture and minerals, round-trip stem transport moisture and minerals are absorbed from soil；Root stores food (the energy money of plant
Source), these foods or used by root, or be digested absorption, postdigestive product strangled skin tissue be transferred to plant soil with
On part；It can make the food of the mankind after the root harvest of some plants；Plant hormone synthesizes in the separate living tissue of root,
It is passed up to aerial part through xylem, so that the growth of plant be promoted to send out the region between the heart and the diaphragm；Root system is impaired, directly affects the strong of plant
Kang Shengchang.Plant stress tolerance refer to plant growth in the tolerance of adverse environmental factor, such as cold resistance, heat-resisting quantity, drought tolerance, water-fast
Property, tolerance to diseases etc..
Inventor is found surprisingly that with 2-cyano-3-amino-3-phenylancryic acetate, probenazole and Metalaxyl-M triple combination, by further investigation one
Compounding shows synergistic effect to the multiple diseases on crops in fixed proportional region, promotes using effect, delays germ to group
Object resistance is closed to generate；Enhance root system of plant, improve the effect of plant stress tolerance and improves crop yield.After further study, complete
At the present invention.
A kind of bactericidal composition (CN103271031) containing 2-cyano-3-amino-3-phenylancryic acetate and Metalaxyl-M, disclose 2-cyano-3-amino-3-phenylancryic acetate with
Metalaxyl-M binary built；The mass ratio of 2-cyano-3-amino-3-phenylancryic acetate and Metalaxyl-M is 1~40: 40~1；The dosage form of bactericidal composition is cream
Oil, suspending agent, wettable powder, water dispersible granules, aqueous emulsion, microemulsion, granule, microcapsule formulations；The document discloses cyanogen
Alkene bacterium ester and Metalaxyl-M binary composition are applied in crop growth period, play prevention and treatment crop disease purpose.With cyanogen alkene of the present invention
Bacterium ester, probenazole and Metalaxyl-M triple combination are for seed processing technology scheme without direct or indirect enlightenment.
A kind of bactericidal composition (CN104041500) of 2-cyano-3-amino-3-phenylancryic acetate-containing and probenazole, discloses probenazole and cyanogen alkene bacterium
The mass ratio of ester is that 1:20 to 20:1 is compounded to sickle-like bacteria with synergistic effect, probenazole and the seed soaking of 2-cyano-3-amino-3-phenylancryic acetate bactericidal composition
Handle the field efficacy to bakanae disease of rice；The dosage form of bactericidal composition is wettable powder, water dispersible granules, suspending agent.With
2-cyano-3-amino-3-phenylancryic acetate, probenazole and Metalaxyl-M triple combination of the present invention are for seed processing technology scheme without direct or indirect enlightenment.
