Abstract

The invention discloses a pre-harvest sweet persimmon preservative. The pre-harvest sweet persimmon preservative is characterized in that natamycin, sec-butylamin and thiophanate-methyl are taken as main agents, one or more components of methyl pyrilamine, chlorothalonil, trichloroisocyanuric acid, sodium dichloroisocyanurate, potassium dichloroisocyanurate, dichlord isocyanurice acid, sodium dichloroisocyanurate, potassium dichloroisocyanurate, sodium chlorite and potassium chlorite are taken as strengthening components to uniformly mix according to a certain proportion. An application method of the pre-harvest sweet persimmon preservative comprises the following steps of: diluting the preservative and water in a weight ratio of 1:100; and spraying the preservative on carpopodium within 24 hours-48 hours before harvesting the sweet persimmons. The pre-harvest sweet persimmon preservative disclosed by the invention is simple in preparation process, low in cost and less in investment. Moreover, the pre-harvest sweet persimmon preservative is convenient to apply, and convenient to operate and apply in production practice. Besides, the pre-harvest sweet persimmon preservative has effects of reducing mildew and decay in storage and transportation of the sweet persimmons, delaying ageing, and keeping the original quality, and further has characteristics of being safe, efficient, free from residues, and good in freshness-keeping effect.

Background technique [0002] my country is the origin of persimmon trees and one of the main producers of persimmon fruit, with a cultivation history of more than 3000 years. However, there have always been problems such as backward production technology, uneven varieties, single structure, and poor commercial properties. Therefore, in order to improve this situation, my country has introduced and cultivated sweet persimmon since 1920 to adjust the cultivation structure of persimmon trees in my country and improve the production and cultivation techniques. [0003] Baoshan, Yunnan has now become one of the country's three major sweet persimmon producing areas, and its area and output are second to none in the country. The fruit of Yunnan Baoshan sweet persimmon can ...
