Termites control in small-scale nurseries of acacia senegal (l.)‎ willd by using some powders from the Neern tree

الملخص EN

This experiment was conducted for two successive seasons 2014 and 2015 under small- scale nursery conditions at Um Dekaka village.

North Kordofan State.

Sudan.

The objective of the experiment was to study the effect of neem leaves and kernel powder for control of termites on Acacia Senegal nurseries.

The experimental design was a randomized complete block design (RCBD) with four replications.

Data was collected for dead seedlings.

The results showed significant differences among all tested rates of neem powders for the two seasons of the experiment.

In the first season (2014), all tested rates of neem kernel and leaves powders significantly decreased the death rate of A.

Senegal seedlings in the nursery.

After four months of treatment, no seedlings death was recorded by the highest rate of neem kernel powder (400 gin2) followed by neem leaves powder at 800 g/m2 which gave 2.5 % death percentage.

For the second season (2015) same trend was noticed.

The combined analysis for the two years revealed that neem kernel powder at 400 g/m2 showed the lowest death rate of the seedlings followed by neem leaves powder at 800 g/m2.

The results suggested that neem kernel at 400 g/m2 and leaves powders at 800 g/m2 are effective and safe options for the control of termites in small - scale nurseries of A Senegal.
