Vineyard insect pests

Uses herbicides/insecticides pre- or post-emergence control of broadleaf weeds in cereals, maize, lucerne, clover, trefoil, grass leys, potatoes, peas, onions, garlics, peas, leeks, soya beans, orchards, groundnuts, strawberries, vineyards and other crops for control of strawberry runners and raspberry suckers and overwintering forms of insect pests on fruit trees also used as a desiccant for leguminous seed crops destruction of potato haulms as a pre-harvest hop defoliant, etc. 

Pests are controlled by actively encouraging, releasing and monitoring beneficial insects and organisms. The Fetzers plant plum trees all around the vineyards to attract the tiny parasitic wasp Anagrus that feeds on leafhoppers. Companion plants such as mustard, crimson clover and sunflowers are planted in rows alternating with permanent covers in the other rows across the entire vineyard to attract other beneficial insects. And ladybirds are introduced to feed on aphids. 

Monitoring In orchards, vineyards and in woodland, glue-traps are used for monitoring purposes (Fig. 8.74). In this way, it is possible to trap, species-specificaUy, the male butterflies, the caterpillars of which are the actual pests. The appearance of insects in these traps allows to determine the exact timing of the insecticide application, and thus to avoid unnecessary spraying.
