“…Areas planted in 2000 for those county-crop combinations were 1800 km 2 for almond and 650 km 2 for the stone fruit. Whether there will be new pest or environmental consequences of increased use of pyrethroids is unknown (76,85).…”

We used the California Pesticide Use Reports to study use of fungicides, bactericides, fumigants, and selected insecticides, primarily for vegetable, fruit, and nut production in California from 1993 to 2000. There were no obvious trends in decreased use of most compounds used to treat plant disease. However, growers have rapidly adopted recently introduced "conventional" compounds. There is very limited use of microbial biocontrol agents to control plant disease and no indication of an increase. We used case studies to explore the potential of different strategies to reduce pesticide use or risk. There have been reductions in use of organophosphate insecticides, largely by substitution with pyrethroids. Theoretically, replacement of "calendar spray" pesticide programs with "environmentally driven" programs could reduce pesticide use in years with lower disease pressure, but this assumes that the majority of growers currently use a "calendar spray" program and that growers who use less than recommended by an environmentally driven program would not increase their use.

“…While promising as an alternative control approach, orchard pyrethroid use has been associated with other problems including pest resistance and suppression of predatory mites (Bentley et al 1987, Zalom et al 1999, 2001a. In this study, the plots treated with esfenvalerate had significantly lower densities of both Aphytis spp.…”

“…Pyrethroid insecticides applied during dormancy have proven to be quite persistent and not very selective, favouring development of insecticide resistance while adversely affecting predaceous mites (Zalom et al 1999(Zalom et al , 2001a. Insecticides in general have also been shown to persist under the hydrophobic covers of scale insects, adversely affecting emerging parasitoids (Cohen et al 1994).…”

Populations of the San Jose scale (SJS), Quadraspidiotus perniciosus (Comstock), and its parasitoids, Encarsia perniciosi (Tower) and Aphytis spp. were monitored with double-sided sticky tape and pheromone traps in an almond orchard. A total of 1.21 ha plots within the orchard were treated during winter dormancy with several insecticides, including horticultural mineral oil alone, oil combined with the organophosphate diazinon at different dilution rates, and oil combined with the pyrethroid esfenvalerate in a completely randomized block design. Higher volume diazinon applications (3750 and 1870 l ha 71 ) proved effective against SJS crawlers, as did esfenvalerate. The higher volume applications had greater deposition on Kromecoat 1 cards placed in the top of the tree canopy, where SJS is most abundant. The lower-volume (935 l ha 71 ) application of diazinon provided control of first-generation crawlers similar to the other diazinon applications, but it was generally less effective in controlling subsequent generations. All insecticide treatments were associated with a reduction of parasitoid numbers, especially the esfenvalerate application.

“…In a variety of field and orchard crops, broad-spectrum insecticides may disrupt the biological control of mites, triggering secondary mite outbreaks that necessitate further pesticide use (Agnello et al 2003;Prischmann et al 2005;Zalom et al 2001). In many instances, substituting more-selective insecticides has helped reduce the severity of these secondary mite infestations and in turn the overall costs of managing orchard pests.…”

“…activity, they kill beneficial insects as well as the targeted pests. The loss of beneficial insects can result in outbreaks of secondary pests such as mites and aphids, necessitating additional treatments and further increasing the potential for negative environmental impacts (Agnello et al 2003;Prischmann et al 2005;Zalom et al 2001).…”
