Uso de la canela (Cinnamomum verum) y molle (Schinus molle L.) Para el manejo de Tetranychus urticae en una variedad de Rosa spp de exportación en el Ecuador

Abstract

Tetranychus urticae Koch is one of the pests that affects different crops such as ornamentals, fruit trees, among others. This pest causes losses of 60% to 80% of production, which is why many farmers use pesticides to combat them that are harmful to the environment and can affect the soil, air, water and the health of those who use these products, it is vitally important to look for new products of natural origin. For this reason, in the present investigation it was proposed to evaluate the efficiency of two types of extracts of cinnamon (Cinnamomum verum) and molle (Schinus molle L.) for the management of the Tetranychus urticae mite in eggs and adults, against a variety of rose of export (Rosa spp). To obtain the extracts, molle fruits and leaves and cinnamon bark were used. The infusion was prepared with 20 g of plant material in 100 ml of distilled water, bringing to a boil for ten minutes, the same process for molle and cinnamon. For the molle and cinnamon extract, 20 g were prepared per 100 ml of distilled water and left to macerate for 48 h, followed by filtration. Thus, 4 treatments and 1 control with distilled water were defined, each with 5 repetitions. The experimental unit was made up of 20 eggs and 20 adults of Tetranychus urticae. In each treatment, 5 ml were used per spray and the evaluation was in three stages at 24, 48 and 72 hours after application. The results indicated that the treatment that acts as acaricide was molle infusion and crude aqueous extract of molle with 83% mortality for adults and molle infusion with 88% mortality for eggs. And low mortality for cinnamon extract with 27% for adults and 24% for eggs. It is concluded that the mo
