Crude extracts of different five plant varieties. t.e. Artemisia alba (wormwood).   Citrollus colocynthis (Bitterapple). Datura annoxia (downy thomapple). Urginia
maritima (Squill) and Aloe vera (aloe) were extracted and prepared as suitable
formulations. The first four plant varieties were extracted using ethanol 95 %, n-
hexane and chloroform. while the fifth one was obtained by cutting its leaves and
collecting the bleeding juice. Some physico-chemical properties of these crude
extracts, such as solubility and free acidity or alkalinity, were determined and
consequently they were formulated as soluble liquIds, and f10wable suspensions or
dust powders. Results obtained indicated that the ethanollc extracts of Artemisia herba alba,
Citrol/us colocynthis pulp, Datura annoxia and Urginia man'tima as well as that of Aloe
vera showed good solubility in water. Therefore they were prepared as soluble liquid
formulations. The rest crude extracts which did not possess such property were
prepared as flowable suspension. Moreover, all the crude extracts were prepared as
dust powders. Soluble liquid formulations showed good miscibility in water, flowable
formulations exhibited good suspensibility and dust powder formulations were fine to
degree less than 40 1.1. All formulations showed suitable free acidity or alkalinity and
passed successfully through heat storage test. Soluble liquid and flowable
formulations may be used for controlling pests on vegetative growth plants, while dust
powders may be utilized against stored grain pests.
