Bionematological Effectiveness of Kompovet B-4 (Waste Product of “Biovet” JSC Peshtera) on “In Vitro” Obtained Vine Crops

ABSTRACT

In the period 2000–2002 in the nematological laboratory of the Sofia University “St. Kliment Ohridski” were executed biological laboratory tests with water extracts of “KOMPOVET B-4” 1:2 and 1:3 with artificial infected with Xiphinema index in vitro small grape vines, (vessel test) with 1 × putting-under of SO₄ and 1 cultivated variety (Cabernet Sauvignon) with control plants infected and watered, and non-infected and watered (1 × week × 100 ml) according to the schedule. It is established that the water extracts of “KOMPOVET B-4” influence fatal (under condition of direct sinking) the nematode Xiphinema index, and the nematodes in the vessel test disappeared total; the water extract stimulate the growth and progress of the test plants, independently of the infection. The best biological effect has been read by extracts with dilution 1:2, concerning the two varieties.
