Pelargonic Acid and Caraway Essential Oil Efficacy on Barnyardgrass (Echinochloa crus-galli (L.) P.Beauv.) and Johnsongrass (Sorghum halepense (L.) Pers.)

Bioherbicides are naturally originated products posing alternatives to synthetic herbicides for weed control. The objective of this study was evaluate the efficacy pelargonic acid and microencapsulated caraway essential oil on barnyardgrass (Echinochloa crus-galli (L.) P.Beauv.) johnsongrass (Sorghum halepense Pers.). Two separate pot experiments were conducted at Agricultural University Athens (spring 2021), arranged in a completely randomized design (CRD) with six control treatments replicated four times. Treatments included applications of: 50 g L?1 (CAR), CAR plus commercial adjuvant (CAR + adj), i.e., alcohol ethoxylate 1.8 L?1, 36.3 (PA), PA (PA tank mixture 64 CAR). An untreated (CON) also included. results current research confirmed knock-down effect against both demonstrated low microcapsules. addition improved but did not appear affect performance acid. No synergistic effects observed between oil. Further is needed optimize use these other natural agriculture as components sustainable integrated management (IWM) systems.
