Abstract

CONTIERO, R.L. et al. Transposition amount of liquid sprayed on sugarcane straw using fan and cone type nozzles. Planta daninha [online]. 2012, vol.30, n.1, pp. 211-216. ISSN 0100-8358.  http://dx.doi.org/10.1590/S0100-83582012000100024.

Raw sugarcane harvest promotes an increase in crop residues of mulch on the soil. This new component changes the dynamics of weed infestation, also acting as a physical and chemical barrier against the action of herbicides. To improve the quality of herbicide deposition on the soil, this study aimed to evaluate the efficiency of spray nozzles and their transposition capacity on sugarcane straw. The experiment was conducted in Maringá-PR, in a completely randomized design, using a factorial scheme 8 x 7, with 8 nozzles (AD 110 02, ADIA 110 02, TT 110 02, TTIA 110 02, CV IA 02, MAG 2, ST 02 and TJ60 110) and 7 increasing amounts of straw (0, 1, 2, 4, 6, 8 and 10 t ha1). It was observed that large quantities of straw reduce the amount of liquid sprayed and deposited on the collecting surface. The spray nozzles anti-drift fan model (AD 110 02) and empty cone with air induction (CV-IA 02) were the most efficient.
