“…In recent years, the management measures for plant diseases have been more appealing for preventive intervention, aiming to reduce costs. Among the alternatives, the recommendation of silicon (Si), although not an essential element for plants, has shown promising results in controlling nematodes in different crops (Rajput et al, 2021;Santos et al, 2021;Alonso et al, 2022). Silicon induced defense mechanisms include: accumulation of lignin, phenolic compounds, increased ascorbic acid concentration, and activation of resistance-related enzymes and phytoalexins, among others (Guerriero et al, 2016;Alonso et al, 2022).…”

Cowpea (Vigna unguiculata (L) Walp) can suffer significant losses due to the attack of Meloidogyne javanica. The most effective control is through nematicides, however, it is an expensive treatment, so alternative measures have been sought. Therefore, the objective was to evaluate the effect of silicon on the control of M. javanica in cowpea plants. The experiment was carried out in a greenhouse, in a completely randomized design, in a 5 × 2 + 1 factorial scheme, being: five doses of Si (0, 60, 120, 180, and 240 mg dm -3 ), two soluble sources of Si (Quimifol Silício® and sodium silicate P.A.), plus an additional treatment consisting of tomato cultivation in soil without the addition of Si and with nematodes, with four replications. Sixty days after inoculation in the plants, the root systems were collected and evaluated: volume, length and fresh mass of roots, gall index, egg mass index, reproduction factor, reproduction index, and reduction of reproductive factor of M. javanica. The sources of silicon at different doses had a positive effect on root variables. They were also able to reduce the parasitism variables of M. javanica in cowpea plants.

The use of silicon (Si) has a physical barrier effect on plant tissues, decreasing nematode infection in different crops. Notwithstanding, research on lettuce crop is lacking, especially regarding the chemical mechanisms of action of this bene cial element. Therefore, this study evaluates the effect of Si supply on lettuce plants infested with 0, 6000, and 12000 eggs and second stage juveniles of M. incognita, both in the absence and in the presence of Si (2 mM) in the nutrient solution. Silicon increases phenolic compounds and ascorbic acid, reducing the M. incognita population and decreasing oxidative stress. It also increases chlorophyll index and the quantum e ciency of the photosystem II (FV/FM), favoring the growth and production of lettuce plants. The use of Si decreased the number of nematodes and affected their reproduction, decreasing the number of eggs and galls in the roots of lettuce plants, being yet another sustainable alternative for the control of M. incognita. The Si bene t would be due to the combined effect of the physical barrier and the chemical action from the increase in phenolic compounds and ascorbic acid in plant tissues, improving the physiological aspects of plants. Key MessagesThe Lactuca sativa is a crop susceptible to the attack of root-knot nematode.The Si strengthens the defense system of this plant against incognita.Si has an effect on increasing the rmness of tissues acting as a physical barrier in control of incognita.Si supply decreases the reproduction rate of incognita. The Si a sustainable alternative, in control of root-knot nematode since its use can reduce applications with nematicides.
