Abstract
The development of new strategies of integrate pest management to improve processing tomato yield and sustainable quality, are requested by the market. This study was carried out to evaluate the effects of foliar applications of glucosinolates and certain medicinal plant essential oils in open field cultivation management. Tomato yield from plots treated with rosemary oil and glucosinolates resulted, on average, significantly higher, until 28%, than that of the control plots. However thyme and oregano oil treated plots showed statistically lower values. Plant vegetative status, including phytosanitary aspects, had the same trend as the production as showed by the exponential regression between two parameters. Findings allow us to conclude that foliar spray of glucosinolates and rosemary essential oils prove to be highly effective treatments inducing increases of tomato yield through plant health improvement.
Highlights
Tomato is a commercially important and most popular annual vegetable crop throughout the world because it is largely required by the market of the fresh and processing industry
Development of new strategies of integrated pest management (IPM) to improve tomato yield and sustainable quality are requested by producers

Summary
Tomato is a commercially important and most popular annual vegetable crop throughout the world because it is largely required by the market of the fresh and processing industry. Disease and pest management is one of the most important productive factors, since tomato plants are susceptible to a number of important pests and diseases which significantly reduce fruit yield and quality, and eventually causing complete crop loss. Development of new strategies of integrated pest management (IPM) to improve tomato yield and sustainable quality are requested by producers. For this scope, here foliar treatments with glucosinolates and essential oils are proposed as potential natural pesticides in open field processing tomato cropping systems. The aim of this paper is to propose the use of glucosinolate containing-tissues from Brassica carinata and essential oils in IPM of tomato cropping systems upon verification of their impact on productive response
