Tomato is one of the important food crops of the world. It has rich essential nutrients features. However, tomato plants are sensitive to certain diseases and pests. This situation causes intense and unconscious pesticide use to avoid crop losses. It is known that mycorrhiza provide many advantages to plant. In this study, the effects of different doses of fungicide applications on some physiological parameters were examined in mycorrhiza applied and non-applied mycorrhiza tomato plants. A pesticide was applied at different doses which were, namely, recommend (R), half of recommend (R/2), and two-fold recommend (R×2). The content of proline, chlorophyll and carotenoid analysis were conducted in the plant samples. Proline values were found low in mycorrhizal than non-mycorrhizal plants in all pesticide doses (P<0.05). However, mycorrhiza*dose interaction was statistically significant (P<0.01). It was found statistically significant in chlorophyll-a (P<0.01), chlorophyll-b (P<0.05), total chlorophyll (P<0.01), and carotenoid (P<0.05) values in terms of mycorrhiza*dose interaction. We suggest that studied arbuscular mycorrhiza may increase at highly the resistance tolerance to fungicide. AMF is suitable option for low chemical input and nature conservation based sustainable agriculture.
