Abstract
Experiments were conducted to study the side effects
insecticide residues on germination, plant growth, flownodulation
of both broad bean and cowpea.
Clay soil was used in all experiments. Insecticides
ested were decamethrin, cypermethrin, fenvalerate, triazophos,
imethoate, profenfos, mephosfolan, disulfoton, lindane, endrin,
DT and methomy1.
These insecticides were used at several concentrations
5, 10, 15, 20, 40, 50, 60, 80 & 100 ppm ), as active
ngredients.
Results indicated that these residues affected the
rminat10n of both broad bean and cowpea plants at concen
rations more thaD 30 ppm at all cases. Some of the inseotici
es tested decreased the percentage of germination also
The soil was irrigated by water to 75 % of its field
apacity. The percentage of germination was recorded after
o days. The side effecttof these residues on plant growth
s recorded.
The number of flowers and number of nodules in treated
d untreated pots were also estimated.
a low concentrations.
All insecticides tested decreased the length of root
a concentrations aore t•han 20 ppm. Some of them.reduced the
ength of stem and some had nearly no effecti specially
t low concentrations.
The phytotoxic symptoms Which appeared in most cases
ere dwarfing, swollen roots, tWisted leaves, discoloration
nd the burnet edges of the leaflets •
.Most of the insecticides decreased the number of
odules specially at concentration more than 10 ppm.
The tested insecticides decreased also the number of
lowers per plant at all concentrations.
Lindane and endrin were detected in broad bean plants.
esidues from both the insectioides tested were found in all
arts of the plant. They were concentrated in roots more
han in the other parts. Lindane was distributed in all
arts of the plant but it _e concentrated at upper”leafets,
while eDdrin was conoentrated in the lower leaflets.
