Abstract

PLS (Positive List System) system, which has been in full operation since 2019, applies the pesticide detection level of 0.01 mg/kg uniformly, expect for pesticides registered for each crop. Minor crops are cultivated at less than 1,000 ha, and cacti and succulents are minor crops. The pesticide industry has avoided the registration of pesticides for cacti and succulents due to economic reasons, so there is a lack of pest information and registered pesticides for these crops. This study was conducted to select fungicides with suitable control effect as well as occurrence patterns on the minor crops which cultivated in small area in Gyeonggi-do. Therefore, this study was carried out not only to control safely with registered fungicides as cultivating cacti and succulents, but also to register fungicides without any harm. We conducted agricultural chemicals evaluation tests of 5 fungicides (oxolinic acid, copper oxychloride + kasugamycin, validamycin A, streptomycin, kasugamycin). Five fungicides were tested for Echeveria. Five fungicides were tested for control of soft rot (Pectobacterium carotovorum). Each test was conducted in the two different places (Goyang and Hwaseong). Fungicides with over 80% germicidial effect after treatment were oxolinic acid and kasugamycin. Other fungicides showed low control values. Damage from agricultural chemicals of them didn’t show. These results indicate that oxolinic acid and kasugamycin can be used for the control of soft rot (P. carotovorum) in succulents.
