Assessment of phytotoxicity of selected botanical insecticides on treated cowpea (Vigna unguiculata) seed
Figure 1 shows the level of malondialdehyde in the seed of cowpea cultivar SAMPEA 11 dressed with botanical insecticides; α-humulene, myristicin and azadirachtin-based insecticides. The level of malondialdehyde in the seed of SAMPEA 11 dressed with botanical insecticides is significantly (P < 0.0...

| Tóm tắt: | Figure 1 shows the level of malondialdehyde in the seed of cowpea cultivar SAMPEA 11 dressed with botanical insecticides; α-humulene, myristicin and azadirachtin-based insecticides. The level of malondialdehyde in the seed of SAMPEA 11 dressed with botanical insecticides is significantly (P < 0.05) lower than that reported for seed dressed with chlorpyrifos but significantly (P < 0.05) higher than that reported for the untreated seed. Figure 2 shows the level of malondialdehyde in seed of cowpea cultivar SAMPEA 12 dressed with botanical insecticides; α-humulene, myristicin and azadirachtin-based insecticides indicating that the level of malondialdehyde reportedly present in seed of SAMPEA 12 dressed with botanical insecticides is significantly (P < 0.05) lower than that reported for seed treated with chlorpyrifos but is significantly (P < 0.05) higher than that reported for its untreated counterpart. Figure 3 shows the level of malondialdehyde in seed of cowpea cultivar SAMPEA 14 dressed with botanical insecticides; α-humulene, myristicin and azadirachtin-based insecticides. The malondialdehyde level in the seed of cowpea cultivar SAMPEA 14 dressed with α-humulene based insecticide is not significantly (P > 0.05) different from that reported for its untreated counterpart. However, the malondialdehyde level in seed dressed with myristicin and azadirachtin based insecticides is higher, than that reported for its untreated counterpart. The malondialdehyde level in seed dressed with botanical insecticides is significantly (P < 0.05) lower than that reported for seed dressed with chlorpyrifos.
