Effects of fungicides use in wheat fields on the damage caused by house sparrow Passer domesticus niloticus (Passeriformes : Passeridae)‎ at Assiut governorate

الملخص EN

This experiment was carried out during the ripening stages of wheat crop.

The trial was aimed to evaluate the effectiveness of different application rates of punch 40% EC., recommended for controlling some wheat pests, as repellent compounds.

Two schedules of spray programme were performed to protect wheat spikes from birds, e.g.

house sparrow Passer domesticus niloticus (L.) (Passeriformes: Passeridae), attack and reduce birds damage.

The results revealed that there were significant differences among concentrations of punch.

The highest protection performance was exhibited by using the recommendation rate of pesticide for controlling pests.

The protection indices (PI%) of tested fungicides were when applied punch (18.75 cm3/100L.water).

The following highest protection indices was attained by applying the second concentration for punch (12.50cm3/100L.water).

The lowest values of protection indices were when applied (6.25 cm3/100L.water).

The results showed that increasing the rate of punch application, resulted to increasing of repellency and protection performance to the wheat spikes during ripening stage.
