Mesotrione: A new herbicide for use in maize

Abstract

In 2000 and 2001 field trials were carried out to evaluate the efficacy of herbicide mesotrione in maize. The experiments were established in Zemun Polje and Smederevska Palanka, according to EPPO/OEPP standard methods. Trade formulation Callisto (a.i. mesotrione 480 g/L) used as a experimental sample in two doses 0.15 L/ha and 0.25 L/ha for pre-em, and 0.15 L/ha adjuvant; 0.25 L/ha + adjuvant and 0.25 L/ha alone for foliar application. The most sensitive weed species were: Adonis aestivalis, Amaranthus retroflexus, Cirsium arvense, Chenopodium album, Chenopodium hibridum Lepidium draba, Brassica nigra, Datura stramonium, Kickia spuria, Polygonum lapathifolium, Sinapis arvensis, Solanum nigrum, Stachys annua i Xanthium strumarium.

U toku 2000. i 2001. godine ispitivana je efikasnost mezotriona, u cilju suzbijanja korova u kukuruzu. Ispitivanja su izvedena na lokalitetima Smederevska Palanka i Zemun Polje, u skladu sa standardnom OEPP/EPPO metodologijom. Primenjen je preparat Callisto (480 g/L mezotriona) u dve količine 0.15 i 0.25 L/ha za zemljišnu primenu, i 0.15 L/ha+okvašivač; 0.25 L/ha+okvašivač i 0.25 L/ha bez okvašivača za folijarno tretiranje. Mezotrion je pokazao veoma visoku efikasnost u suzbijanju širokolisnih korova, kao što su: Adonis aestivalis, Amaranthus retroflexus, Chenopodium album Chenopodium hibridum, Cirsium arvense, Lepidium draba, Brassica nigra Datura stramonium, Kickia spuria, Polygonum lapathifolium, Sinapis arvensis Solanum nigrum, Stachys annua i Xanthium strumarium.
