Induction of resistance in bean against concha Epilachna varivestis with nutrition and homeopathy

Abstract

The pest insect control with organosynthetic pesticides provoke many problems; for this reason, many alternatives have been implemented. However, these ones have not been included to reach a better management. This research was conducted to evaluate the effect of the mineral fertilization or organic without fertilizing it, conventional soil or organic and with or without agronosodes homeopathic in the development of the bean´s shell and also the foliage damage of the old one.

To this effect, bean was planted with these treatments and it was offered as plant or cut leaf to ten maggots of first instar in two experiments. The different parameters in the insect biology and the daily foliage damage of the old one were evaluated. The compost at one and three tons ha-1, and the organic soil, independently, reduce from 7 to 14.6% the larval duration regards to the mineral fertilization and to the conventional soil and doses of 1.8 to 3.6 t ha-1 and the agronosode at 200CH reduce in 50% or more the adult foliage damage, but combined lose the effect. The organic combine soil with agronosode at 200CH reduces in 85.7% the pupal viability. The organic soil integration with compost 3 t ha-1 of compost or with agronosode at 200CH prejudices the insect and protects the crop.
