食品伙伴網(wǎng)訊    據(jù)加拿大衛(wèi)生部消息，9月11日加拿大衛(wèi)生部發(fā)布PRD2015-23號征求意見文件，有害生物管理局（PMRA）擬批準(zhǔn)登記磷酸鉀鹽和磷酸二鉀鹽（Mono- and Di-Potassium Salts of Phosphorous Acid）銷售和使用，用于防治溫室黃瓜的霜霉病。征求意見截止日期為2015年10月26日。

    目前加拿大已批準(zhǔn)磷酸鉀鹽和磷酸二鉀鹽作為幾種蔬果的葉面殺菌劑以及土豆的采后處理。

    部分原文報道如下：

    Mono- and di-potassium salts of phosphorous acid （commonly known as phosphorous acid） are phosphonate fungicides belonging to the Group 33 class of fungicides as designated by the Fungicide Resistance Action Committee. It may inhibit the metabolism of susceptible fungal pathogens, and stimulate the plant's natural defence response to pathogen attack. Mono- and di-potassium salts of phosphorous acid are currently registered in Canada as a foliar fungicide on certain vegetables and fruits, and a post-harvest treatment on stored potatoes.
