A few days ago, some media reported that some apple farmers in the apple-producing areas used fruit bags with pesticides and anti- fertilizers to wrap the young fruits. The apples were directly contacted with pesticides until they matured. For a time, fruits, medicine bags, and pesticide residues have become the key words of concern.
In an interview with the reporter, experts said that the key to judging whether a fruit is safe is whether the amount of pesticide residues exceeds the standard. The key to determining whether the pesticide residue exceeds the standard is the time between the last contact with the pesticide and the consumer market.
Since there are double-layer paper bags, why should fruit farmers use medicine bags? Xiao Bian pointed out that because the plain paper bag can not be completely closed on the fruit, there will still be bugs that may crawl into the bag and smash the fruit, so some farmers will use the medicine bag to kill the insects.
Professor Liang Huairui, an academician of the Chinese Academy of Engineering, also pointed out in an interview with the media that after apple bagging, the humidity inside the bag increases, and the probability of being infected by bacterial diseases is relatively increased. It is more common that apples may have long black spots. Both the bacteriostatic and the hydrazine are commonly used fungicides . After applying the diluted dose of the appropriate proportion to the fruit bag, it can prevent the growth of bacteria to a certain extent and reduce the harm to the apple. However, due to the fact that the production of “pharmaceutical bags†has not yet been approved in China, the “medicine bags†used by a small number of farmers are mostly produced in small workshops. The proportion of blending is inconsistent. The actual effect is quite different after applying “medicine bagsâ€.
The relevant person in charge of the Qixia Agriculture Bureau said to the media, “The rise of medicine bags is a matter of recent years,†individual fruit farmers use medicine bagging. The medicine bags used are diluted with pesticides and rolled and coated with improved fruit bag machine. Inside the bag. Many fruit farmers in Qixia City said that they can reduce the number of pesticides used after using this medicine bag. The grown apples are good, and the others are no different from ordinary paper bags.
Shu Huai Rui said that both the bacteriostat and the thiram are pesticides allowed in the country. In particular, Fukumi has no better alternatives in controlling apple rot. Before the bag is popular, the two drugs are sprayed directly onto the tree. The apple is in direct contact. Usually, it can be stopped 60 days before the picking period, and it does not affect the normal consumption of the apple.
