Control of root-knot nematodes on lettuce and cantaloupe in a plastic house in Tuscany [Meloidogyne spp. - Lactuca sativa L. - Cucumis melo L.]
Methyl bromide was tested against root-knot nematodes in the Province of Grosseto in a plastic house at the rate of 20, 40, 60 and 80 g/square m under either standard plastic tarping or virtually impermeable film (Bromotec). After application in October 1994, lettuce was planted and harvested in Jan...

Zusammenfassung: | Methyl bromide was tested against root-knot nematodes in the Province of Grosseto in a plastic house at the rate of 20, 40, 60 and 80 g/square m under either standard plastic tarping or virtually impermeable film (Bromotec). After application in October 1994, lettuce was planted and harvested in January 1995. In March, without any further treatment, cantaloupe was cropped until June-July. Treatments were very effective on both crops. Yields were greatly increased and nematode populations in the soil and nematode attacks on the roots were dramatically reduced. However, there were no statistical differences between rates of application of the chemical and type of tarping
E' stata saggiata l'efficacia del bromuro di metile contro i nematodi galligeni in provincia di Grosseto. Il fumigante e' stato somministrato al terreno, in una serra di plastica non riscaldata, alle dosi di 20, 40, 60 e 80 g/metri quadrati sotto coperture plastiche di tipo standard o impermeabile ai gas (Bromotec) in ottobre 1994. Dopo il trattamento e' stata piantata della lattuga, raccolta nel gennaio 1995, ed in marzo, senza alcun ulteriore trattamento, e' stato messo a dimora melone, raccolto in giugno-luglio. I trattamenti hanno protetto efficacemente le due colture incrementando notevolmente le produzioni e riducendo a livelli pressoche' non determinabili le popolazioni di Meloidogyne nel terreno ed il grado di infestazione sulle radici. Non sono state osservate differenze statisticamente significative tra le dosi di somministrazione e tra i tipi di copertura plastica |
