Caterpillars on Cannabis Plants
Avoid butterflies and moths! Although these beautiful creatures look great resting on your cannabis plants, they lay eggs that hatch into caterpillars! Don’t let them hang around your garden! Butterflies generally deposit their eggs prior to the arrival of the winter season, so these eggs will hatch when ambient temperatures are the appropriate, needing the heat of the end of summer, which coincides with the arrival of winter in about two months. It is very feasible that butterflies deposit their eggs and these don’t hatch until appropriate conditions prevail.We must thoroughly observe the plant, looking at those leaves or buds that are found in the highest parts of the plants, where butterflies lay their eggs. At first sight it’s really complicated to be able to see the eggs, but if we carefully examine the plant they will be distinguished as small sets of dots that acquire different colours (white/yellow) and shapes (round or oval), depending on the type of butterfly egg.
After this initial inspection – and during the whole flowering period – we must look at the buds, starting at the top and thoroughly examining the rest of the plant in search of small black remains or darker parts of the buds, which are sign of rottenness. The first attacked flowers are the bigger ones, but without being extremely compact, so caterpillars can easily pierce them and devour the softer tissues, such as the small branches of the lower parts of the buds.Locate the butterflies that lay down on the plants. Look for eggs on the leafs. During the flowering phase, control the buds looking for signs of bites. In case of detection, apply Biothur or another product against caterpillars. Stop applying the product within the last 15 days. Review the plants and buds after harvest and remove the infected or bitten parts. Capture the caterpillars by hand in the case of not being able to apply the product. Leave comments or questions below!
