Influence of calcium silicate application on the population of Aproaerema modicella Deventer (Lepidoptera: Gelechiidae) on groundnut

Abstract

Field experiments with foliar application of calcium silicate @ 2.0, 3.5 and 5.0 per cent, soil drenching of calcium silicate @ 10.0, 15.0 and 20.0 per cent and combination of foliar and soil drenching (@ 2.0% + 20.0%, 3.5% + 15.0% and 5.0% + 10.0%) were evaluated on 20 days old groundnut plant and compared with an untreated check. Application of calcium silicate via foliage and soil simultaneously @ 5 and 10 per cent on 20 days after dibbling of groundnut was effective to reduce the population of leaf miner and their leaflet damage, recording mean population of 5.25 nos. of larvae/10 plants and 16.46 per cent leaflet damage, respectively, while it was 12.25 nos. of larvae/10 plants and 27.95 per cent leaflet damage in untreated control. Reduction in population of leaf miner in groundnut might be due to silica induced plant defensive enzymes, however, the moderate reduction in population of leaf miner pest in groundnut can be well explained due to the high accumulation of silica in groundnut plants.

Influence of Calcium Silicate on the Chemical Properties of Pleurotus ostreatus var. florida (Jacq.) P. Kumm

“…Silicon (Si) is the second most abundant element in the earth’s crust and its effect on organisms may be different, serving as a cellular chemical element or providing a natural morphological modification [ 7 , 8 , 9 , 10 , 11 ]. As a cellular chemical element, it plays an important role in the mineral nutrition of plants, aiding development by increasing the organism’s biomass.…”

Different Silicon Application Sources and Factors Influencing Mandibular Wear in Sugarcane Early Shoot Borer, Chilo infuscatellus Walker

“…Arivuselvi et al [17] who reported that the rice plants treated with sodium metasilicate at 2t/ha recorded maximum silica content (9.88%) followed by calcium silicate at 2t/ha treated plants (9.03%) resulted in the reduced the incidence of brown plant hopper. Parthiban et al [27] who reported that the foliar spray of calcium silicate at 5.0% reduced the population of leaf miner in groundnut was due to high accumulation of silica in groundnut plants.…”
