Sažetak
Field studies were conducted at the experimental station Šašinovečki Lug near Zagreb in 2005. to evaluate weed control and spinach response to preemergence and postemergence treatments with different herbicides applied alone or in tank mixtures. Lenacil et 640 g a.i./ha pre-em + (desmedipham+phenmedipham+ethofumesate 63+49+77 g a.i./ha) post-em; S-dimethenamid 576 g a.i./ha pre-em; (desmedipham+phenmedipham at 40 + 40 g a.i./ha) + (desmedipham+phenmedipham 56 + 56 g a.i./ha) post em; (desmedipham+phenmedipham + ethofumesate 30+30+30 g a.i./ha) + (desmedipham+phenmedipham+ethofumesate at 42+42+42 g a.i./ha) post-em and chloridazon 390 g a.i./ha + (desmedipham +phenmedipham 40+40 g a.i./ha) early post-em + chloridazon at 390 g a.i./ha + (desmedipham +phenmedipham+ethofumesate at 35+45+55 g a.i./ha) post-emergence were applied. Mineral oil or surfactant were added in all tank mixtures. Herbicide treatments reduced number of Ambrosia artemisiifolia and Echinochloa crus-galli plants by 44,4 to 81,5 %. Application of dimethenamide resulted in slight injury to spinach.
