に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] The present invention comprises a synthetic resin emulsion polymer, calcium carbonate powder (hereinafter referred to as calcium carbonate powder) and a dispersant as main components, and the calcium carbonate powder is dispersed and diluted in water. The present invention relates to a fruit surface-protecting agent for improving fruit quality, which is difficult to settle and separate, adheres more to fruits when sprayed, and is extremely unlikely to flow out due to rainfall.

れている。At present, as a calcium carbonate wettable powder, a formulation containing calcium carbonate powder and a spreading agent as main components is dispersed and suspended in water on the fruit surface of a tree, and this is sprayed to protect the fruit surface. Quality improvement, that is, acid reduction, sugar increase, coloring promotion, skin roughening prevention, skin peeling prevention, promotion of pretreatment, and improvement of storability have been attempted.

展着剤の開発が望まれていた。Since a water-soluble organic polymer is usually used as the spreading agent, the formulation easily flows due to rainfall, which is just another step to improve the sustainability of the fruit surface protection effect. Development was desired.

づまりが発生したりした。On the other hand, there is also a method of using an aqueous emulsion of a synthetic resin obtained by emulsion polymerization as a spreading agent. (Japanese Patent Publication No. 45-31
69) In this case, the dry film is essentially insoluble in water, so there is little risk of it spilling out due to rainfall, but since the synthetic resin aqueous emulsion has an extremely low viscosity at the same concentration compared to an aqueous solution of a water-soluble organic polymer, In addition, when the formulation is stored in a solution state, and when the fruits are coated with this formulation, it is diluted 50 to 100 times and applied by spraying. Sedimentation and separation of powder occurred, and effective coating could not be performed, and nozzle clogging occurred.

Attempts were made to add sodium hexametaphosphate, potassium tripolyphosphate, sodium pyrophosphate and the like.
その結果、沈降安定性は或る程度改善されたが、果面の

増加した。As a result, although the sedimentation stability was improved to some extent, the amount of adhesion on the fruit surface was extremely small, and the amount of runoff due to rainfall increased rather.
