Abstract
The invention relates to ethirimol water dispersible granules. The ethirimol water dispersible granules in the invention adopt efficient disintegrant and dispersing auxiliary and have the advantages of high disintegration speed, high suspension rate, stable product quality and the like. The application of synergist salicylic acid and salt thereof can dramatically improve control efficiency of ethirimol water dispersible granules and reduce dosage.
Description
Technical field
The present invention relates to a kind of pesticide water dispersible granules, especially relate to a kind of ethirimol water dispersible granules.
Background technology
Water dispersible granules is because of its active constituent content height, and no dust easily measures, good stability, and advantages such as convenience, safety are stored and are used in transportation, are rapidly developed in recent years.
The chemical name of the phonetic phenol of second is 5-butyl-2-ethylamino-6-methylpyrimidine-4-alcohol, belongs to the miazines bactericide, absorption in the tool.Can be by blade and root absorption, suction in producing, protection and therapeutic action are mainly used in the powdery mildew of preventing and treating various crops.The phonetic phenol suspending agent registration of 25% second is only arranged at present, and formulation is single.
Salicylic acid is a septichen, claims " antiphlogistic " of plant again, and microorganism is had antibiotic property, extensively is present in the higher plant.Salicylic acid is again a kind of phenols hormone, is also bringing into play important physiological action in plant corpus, can not only regulate some growth and development processes of plant, also the plant antibiont coerce with abiotic stress in bringing into play important effect.Plant is after being subjected to virus, bacterial invasion, the salicylic acid level that is infected the position can significantly increase, the protect from infection diffusion at position of downright bad scab occurs, the salicylic acid content of non-infection site also can raise in addition, thereby makes it infect the generation resistance again to pathogen.
Summary of the invention
The purpose of this invention is to provide a kind of ethirimol water dispersible granules.
