Oil suspended agent for preventing fruit dropping as well as preparation method and application thereof

Abstract

The invention discloses an oil suspended agent for preventing fruit dropping as well as a preparation method and application thereof. The oil suspended agent for preventing the fruit dropping comprises the following components by weight percent: 1 to 40 percent of 1-methyl cyclopropene microcapsule granules, 1 to 10 percent of dispersing agent, 0.1 to 10 percent of thickening agent, 0.1 to 10 percent of stabilizing agent, and the balance of liquid carrier, wherein the content of 1-methyl cyclopropene in the oil suspended agent is 0.01 to 2 percent. The oil suspended agent has small particle size, and excellent emulsification performance, dispersity, spreading performance, viscosity, suspension rate and shelf life stability under the joint effect of the additives dispersing agent, thickening agent, stabilizer and the liquid vector; after being applied, the chemical effect can be continuously played in a given time, the chemical liquid is uniform in distribution in an open orchard environment, the acting time is ensured, the effect for preventing the dropping of fruits in a fruit picking period is good, and the harvesting time can be prolonged.

Description

technical field [0001] The invention relates to a preparation for preventing fruit drop, in particular to an oil suspension for preventing fruit drop and its preparation method and application. Background technique [0002] In order to reduce the loss of the fruit industry, relevant work can be carried out from two aspects of preventing fruit drop and post-preservation. At present, the method of preventing fruit drop mainly starts from two aspects: one is the cultural method, which suppresses the balance between plant growth and reproductive growth through fertilizer and water control, thinning flower buds, flowering girdling, etc.; the other is the use of plant growth regulation to To regulate the physiological state of fruit trees, it is generally used in the current production to spray gibberellin on the orchard before and after flowering and spray NAA before harvest. However, although spraying gibberellin can prevent flower and fruit drop, it will make the weight of the...

Problems solved by technology

If directly process citrus with 1-methylcyclopropene, because the type of preparation directly used by 1-methylcyclopropene is a fumigant, the effect of the fumigant as spraying is very unsatisfactory; if it is made into a preparation, but the patent document There is no record of what type of preparation was made, let alone what advantages or technical problems it overcomes when making this type of preparation for spraying citrus

[0006] In short, on the one hand, for 1-methylcyclopropene fumigant, the 1-methylcyclopropene fumigant is put into water, the active ingredient 1-methylcyclopropene is released in a closed environment, and the target crops are treated in a closed environment. , and when it is used as spraying, it is impossible to seal the field orchard, which will greatly reduce the effect of 1-methylcyclopropene and greatly reduce the economic value; on the other hand, 1-methylcyclopropene fumigant has no special excipient The agent cannot be applied with oil or water, and excellent suspension performance and dispersion performance cannot be obtained, resulting in uneven distribution of the agent, clogging of the nozzle, etc.
