| Few control methods are available in Norwegian organic fruit production that can prevent damage by early and late larvae. Also phytophagous mites are difficult to control without harming the beneficial mites. Proc-essed kaolin function by coating trees and thus creating a physical barrier to infestation, impeding move-ment, feeding and egg-laying. Kaolin may reduce feeding and movement of over-wintering tortricide larvae and other larvae that hatch early in spring and have a repellent effect against egg-laying tortricide females in summer. Kaolin may also have a control effect against mites as it clings to the body and reduce feeding. Tri-als with kaolin were conducted in 2003, 2004 and 2005 in plum and apple orchards. Results show that kaolin reduces the... |

| True bugs (Hemiptera; Heteroptera) are important pests in fruit production in Norway. In organic fruit pro-duction they may damage up to 40% of the crop. Several of the Heteropteran species attacking apple and pear are polyphagous, with many other hostplants than pome fruit. In organic production few control meth-ods are available against bugs. In this study we have tried a cultural control method (mowing of ground-cover) as well as spray applications of various biological insecticides against bugs. Spray application of azadirachtin (NeemAzal), rape oil and garlic extract (Ecoguard) were tested. Results indicate that the effect of mowing groundcover inside the orchard is variable and small. Applying NeemAzal reduced the number of bugs and damage. Oil and... |
