Abstract

Concentrate sprays gave equal or near equal control against insects and mites on pears, prunes, peaches and almonds when compared with dilute sprays in last season's tests in Northern California orchards. Possible advantages in the use of concentrate sprayers include reductions in the amount of water needed and number of fills now used per acre in dilute spraying (40 to 80 vs. 300 to 1500 gallons per acre). The amount of pesticide used per acre can also be reduced by 25 to 40 per cent. Reductions are also possible in time and man hours per job as well as sprayer costs and maintenance with use of concentrate spraying equipment. No phytotoxic effects were caused by any of the spray test applications.
