摘要:

In an experiment, house crows(Corvus splendens)were estimated to damage 65.1% of sprouting sunflower(Helianthus annuus)seedlings at Ludhiana, Punjab (India). Seed treatments with 0.5% thiram (tetramethylthiuram sulphide) and 0.5% copper oxychloride [3Cu(OH)2CuCI2], both commonly used fungicides, did not reduce bird damage. The number of seedlings in a plot from which birds were excluded by netting was significantly greater than, that in any of the chemical treatments as well as in the untreated control.
