Dimethyl disulfide (DMDS), the natural biopesticide extracted from Allium spp., was evaluated against root-knot nematode (Meloidogyne incognita) of tomato (Lycopersicon esculentum L.) in greenhouse pot culture. All concentrations of DMDS viz. 30 ml, 60 ml, and 80 ml and Aldicarb @ 2g per square meter of soil were effective against root-knot disease under both wet and dry conditions of soil. Nematode incidence was reduced drastically by higher dose of DMDS and Aldicarb @ 2g but did not accelerate vegetative growth of tomato plant especially when tomato seedlings were transplanted immediately after soil treatment. Low concentration of DMDS (30 ml per square meter of soil) was found appropriate for controlling root-knot nematode of tomato, accelerating saprophytic nematode population in soil and also enhancing vegetative growth of tomato plant under dry condition of soil.   DOI: http://dx.doi.org/10.3329/bjar.v36i4.11759   Bangladesh J.

We previously reported that napropamide [2-(α-naphthoxy)-N,N-diethylpropionamide] was highly toxic to achlorophyllous callus of tomato (Lycopersicon esculentum Mill. ‘San Marzano’), whereas foliar application to seedlings was almost without effect. Experiments were performed to ascertain the effects of napropamide on green and achlorophyllous calli of tomato and broadleaf dock (Rumex obtusifolius L.). The growth of achlorophyllous tissues was more severely inhibited. Foliar applications were not as inhibitory in both species. Napropamide was applied to tomato seedlings via roots and cut shoots and root growth was more inhibited than shoot growth. Thus napropamide is toxic to achlorophyllous tissue and is either less toxic to, or detoxified by green tissue.

Abstract A description is provided for Phytophthora citricola. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Antirrhinum majus, Brachychiton populneum, Ceanothus sp., Citrus spp., Erica hiemalis, Hibiscus spp., Humulus lupulus, Lycopersicon esculentum, Malus pumila, Primula japonica, Rhododendron catawbiense, Ribes grossularia, Rosa sp., Rubus idaeus, Schinus moue and Syringa vulgaris. Also pathogenic on inoculation to: Chamaecyparis sp., Cupressus sp., Cydonia oblonga, Euphorbia resinifera, Lycopersicon esculentum, Malus pumila, Phaseolus vulgaris and Pinus sp. (Waterhouse, 1957; 39: 249; 40: 433; Herb. IMI.) DISEASES: Brown rot of oranges, black root of hops, root rot and cane die-back of raspberry, die-back of rhododendron and basal rot of tomato seedlings. GEOGRAPHICAL DISTRIBUTION: Africa (South Africa); Asia (Formosa), Australasia & Oceania (Australia, New Zealand); Europe (Great Britain, Germany, Italy (Sicily)); Central America & West Indies (Antilles); North America (U.S.A.); South America (Argentina). TRANSMISSION: Soil-borne. Survives as mycelium in host roots and as oospores in soil (45, 3381b). Also intercepted once in Czechoslovakia on oranges imported from Turkey (42: 197).
