Abstract: The aim of this study had been to appraise efficacy of biocidal substances, made from aqueous essences of Calotopis procera and Crataeva religiosa, on main pests to cabbage. Tests concerned essences of Calotopis procera or Crataeva religiosa used alone, and a mixture of both substances. Results point out that essence from Calotopis has shown a significant effect on Plutella xylostella and Hellula undalis grubs, with P-values of 0.0289 and 0.0253, respectively, both inferior to 0.05, threshold of significance. Essence from C. religiosa has been effective on Spodoptera littoralis, but has got a limited impact on Plutella and Hellula with respective P-values of 0.36 and 0.54. The mixed product, for its part, has not given any significant effect on these pests. Besides their biocidal effect, essences from Calotropis have had an impact on both crops maturation and weight. The other biocidal matters have influence on plants weight too, but in a moderate way, compared to Crataeva.
