Abstract:We assessed the influence of nine biopesticides on adults and larvae of western flower thrips (WFT), Frankliniella occidentalis (Pergande) and its predator, the anthocorid Orius laevigatus (Fieber) under Mediterranean greenhouse conditions. Trials were carried out in a strawberry crop where both species had naturally established. Foliar sprays were applied weekly for one month. Treatments did not provide sufficient control of larval and adult F. occidentalis. The negative effects on the dynamics of the predator were evident only with the use of some specific products. The botanical insecticides rotenone and neem, and the nematode Steinernema feltiae (Filipjev) reduced O. laevigatus numbers, and these effect are evident in the adult stage of O. laevigatus. Such products have determined a reduction of the population of the predator from the first treatments even if the incidence was not very high. We conclude that the use of some botanical pesticides and nematodes against WFT is uneconomical and possibly disadvantageous where there is an established predator-prey population.

“…Measuring agrichemical use accurately to record aspects of its use is a legislative requirement in many countries. In New Zealand, Cameron et al (2009) demonstrated the benefits from recording insecticide use by associating the reduction of insecticide use in process tomatoes in conjunction with the implementation of integrated pest management for sustained control of the main insect pest Helicoverpa armigera. Walker et al (2009) recorded growers that followed integrated fruit production guidelines in apple orchards reduced insecticide loadings by 80% and fungicide loadings by 45%, with both apple and wine sectors reducing the use of agrichemicals that are potentially toxic to aquatic ecosystems.…”

“…3). This decline has been attributed to the implementation of IPM procedures such as crop monitoring and pest action thresholds (Cameron et al 2009). The general trend of increasing annual fungicide use indicates that the lower number of spray operations initiated by the reduced need for insecticides did not influence decisions on disease control.…”

“…Pest and disease control is usually regulated by the local processing company and, from 1995, applications of pesticides have been based on information from crop scouts using methods developed in an integrated pest management (IPM) programme (Herman 1995). The influence of that programme on insecticide use over time has already been examined (Cameron et al 2009), and the same pesticide use database has provided the information to document fungicide use in this paper.…”

Fungicide use in processing (field) tomatoes from 1995 to 2009 on the East Coast of the North Island of New Zealand has been documented using data extracted from growers' annual spray diary records. During this period, 26 different fungicides*some of which are also used as bactericides*were used by growers to control a range of plant diseases. The number of fungicide applications to each crop ranged from 10 to 28, with fewer applications in very dry seasons. Inorganic copper (mainly copper hydroxide), applied to control both bacterial and fungal diseases, was the most commonly used material, followed by chemicals in the dithiocarbamate, chloro-nitrile and pyridinamine groups. These four multi-site 'protective' fungicide groups accounted for 90% of all disease-control products used during the 15-year period. Site-specific fungicides (e.g. benzimidazoles, phenylamides, dicarboximides, dimethomorph and strobilurins) were used much less frequently. The exclusive use of fungicides at risk from fungicide resistance development (most commonly the site-specific fungicides) was generally avoided and therefore overall risk of the development of fungicide resistance in processing tomatoes in Hawke's Bay is believed to be low. This study demonstrated that the number of fungicide applications per crop has increased about two-fold since 1995 while, during the same period, insecticide applications decreased.
