Abstract
2-Chloro-2, ‘6’-diethyl-N-(methoxymethyl)acetanilide (alachlor), 4-chloro-5-(dimethylamino)-2-(α,α,α-trifluro-m-tolyl)-3 (2H) pyridazinone (SAN-6706), and 4-chloro-5-(methylamino)-2-(α,α,α-trifluoro-m-tolyl)-3(2H)-pyridazinone (SAN-9789) were applied to ‘Early Black’ cranberry vines in the spring at rates of 8, 12, and 16 lb. active ingredient/acre. No phytotoxicity on vine growth or appearance was detected in the alachlor plots or in plots receiving lower rates (8 and 12 lb./acre) of SAN-6706 and SAN-9789 but the higher rate caused a temporary chlorosis at the base of the cranberry leaf blade. No significant differences were detected between untreated and treated berries in respect to yield and berry size, dry wt, pectin content, and anthocyanin development.
Abstract
The experimental herbicide 2-(naphthoxy-N,N-diethylpropionamide (R-7465) was compared with Morcran [a formulated mixture of sodium N-1-naphtylphthalamate (naptalam) and isopropyl m-chlorocarbanilate (chlorpropham)] and dichlorobenzonitrile (dichlobenil) on fruit development of cranberry (Vaccinium macrocarpon cv. Early Black). R-7465 had no significant influence on yield, berry size, berry dry weight, pectin content, or anthocyanin development.
