Calcium silicate and organic mineral fertilizer increase the resistance of tomato plants to Frankliniella schultzei
Phytoparasitica 37 (3), 225-230
Abstract: Frankliniella schultzei Trybon (Thysanoptera: Thripidae) is an important pest of tomato plants. The need for more healthful foods is stimulating the development of techniques to increase plant resistance to phytophagous insects. The objective of this research was to evaluate the effect of calcium silicate and an organic mineral fertilizer, alone or in combination, on the resistance of tomato plants to F. schultzei. The treatments consisted of: control (T1), calcium silicate (T2), organic mineral fertilizer (T3), and calcium silicate with organic mineral fertilizer (T4). The mortality of nymphs of this thrips and the number of lesions on tomato leaves were evaluated after three, six, nine and 12 applications of these products. The number of F. schultzei individuals and of lesions on tomato leaves was lower in treatments T2 and T4 than in T1 and T3, showing a possible increase in tomato resistance to this pest. The increase in the number of applications of calcium silicate and the organic mineral fertilizer increased the mortality of nymphs and reduced the damage by this insect on tomato leaves, mainly after nine applications.
