Brazilian company Grupo Vittia has registered a biological insecticide that will help farmers fight whiteflies, green aphids, pink aphids, cotton aphids and other pests. Internet information portal Fertilizer Daily. Grupo Vittia is based on the chrysopid larva, a natural predator useful for some agricultural and horticultural crops.
Aphids are a fairly common pest, insects cause yellowing and browning of the leaves. The aphid population can increase 10 times in a week, so their spread can cause great losses. At high population density, up to 50% of production can be lost.
The whitefly sucks the juice of plants, causing changes in their vegetative and reproductive development, weakening them and reducing the productivity and quality of fruits.
According to the Brazilian Agricultural Research Corporation, at high population density, up to 50% of production can be lost.
Criso-Vit should be applied in plantations with a distance of 20 m, or with drones, guaranteeing high yields in the cultivated area.
