Abstract

Testing of the control power of the paraquat dichloride herbicide in suppressing weed growth in immature coffee cultivation was carried out in Sumber Jaya, West Lampung in May-August 2023. The research aimed to obtain an effective dose of paraquat dichloride and determine its phytotoxicity to coffee plants. The treatments consisted of 5 levels of paraquat dichloride dosage, namely 276 g ha-1(B1); 414 g ha-1(B2); 552 g ha-1(B3); 690 g ha-1(B4); and 828 g ha-1(B5) and compared with manual weeding treatment (B6) and control (no treatment) (B7). The research used a Randomized Block Design (RBD) with 4 repetitions. Based on the research results, it can be seen that paraquat dichloride at a dose of 552 - 828 g ha-1 was effective in suppressing the total weed growth of the dominant weeds Asystasia gangetica, Ageratum conyzoides, Synedrella nodiflora, Ottochloa nodosa, Paspalum conjugatum, and Richardia brasiliensis until 8 days after application (DAA). Application of paraquat dichloride at a dose of 414 - 828 g ha-1 was able to control the growth of A. conyzoides and S. nodiflora weeds until 8 DAA. Application of paraquat dichloride at a dose of 276 - 828 g ha-1 on immature coffee plants did not cause symptoms of poisoning.
