| Abstract: |
Insect’s infestation development on guar plants in Kaha region, Qalyoubia Governorale, during 2016 and 2017 seasons was estimated. Four insecticides were sprayed on guar plants and their effect on the whitefly, Bemisia tabaci and the cotton aphid, Aphis gossypii and the seeds’ yield were estimated, to choose the suitable pesticide that may improve plant protection for better performance of guar. Significant decreases were noticed in insect’s population of all treatments with increasing successive sprays. The yield of guar seeds was highest by application of natural oil (437.69 kg. / feddan) followed by the botanical extract Azadirachtin (393.78 kg.) , opposed to 250.2 kg. for the control treatment. |
