1 Residual life of this material is short; extend effectiveness by combining with 1/2 rate of 15. Available for nectarines by 24(c) label in Virginia and West Virginia.
2 Cicada immigration from unsprayed areas necessitates frequent applications for effective control. See maps, Fig. 2, for location and year of cicada emergence.
3 Pyrethroids give good control of adults. Monitor with pheromone trap for proper timing. Mites can be expected to increase if pyrethroids are used at this time. Monitor them closely. If adults are not controlled now, other recommendations for larval control are given under second cover spray.
4 Sevin XLR PLUS is safer for honey bees, mainly when used in concentrate sprays of 25 gallons per acre (1:39 dilution ratio). However some additional bee safety over Sevin 50W is obtained when applied in more dilute sprays.
5 Mating disruption for OFM should be applied before first flight of second generation (Figure 3). Be sure to read note on mating disruption on note, p. 36.
