Using Trap Plants For Pest Control
by. OGF member POTential
Sometimes it's wise to use trap plants to control pest problems. for example, if you encounter a pest during flowering and it's no longer safe to use pesticide sprays on your cannabis plants, a trap plant that the pest prefers to cannabis can be placed in close proximity to the flowering cannabis to attract the pest.
there are 3 different modes of action you can make use of. first, some plants catch bugs - carnivorous plants; second, you can treat the trap plants with insecticides so that visitors die; third, you can regularly dispose of trap plants.
you should always start your own trap plants from seed or cutting so that you don't introduce pests from nursery plants. here are some options for trap plants:
for flying pests like fungus gnats & winged root aphids, the drosera capensis, aka cape sundew. this plant is easily propagated from stem cuttings. buy one from a nursery, make it into a lot of plants, put them all over the room. don't fertilize these plants - only water them. look up cook's carnivorous plants here in oregon, near eugene. you can also get seeds.
spider mites prefer hibiscus to cannabis. treat the hibiscus with avid/floramite/shuttle/forbid and place it into direct contact with an infested plant so that the mites can migrate. there are a lot of different types of hibiscus, and i have no clue which are most attractive to mites. i picked hibiscus radiatus because its foliage looks similar to cannabis.
thrips like clover more than cannabis. treat the clover with avid or conserveSC (spinosad). clover seed is readily available, inexpensive, sprouts and grows quickly.
aphids love nasturtiums. there's one pesticide in particular that is extremely effective against aphids: imidacloprid. we can't use it on cannabis because it's fully systemic and long lasting, so a cannabis plant treated at any stage of life is likely to have residue in the flowers at harvest. that's not safe to ingest or inhale. but we can use it on nasturtiums (as long as you're not planning to eat the nasturtium leaves or flowers - they're edible, taste kind of peppery). use the imidacloprid as a soil drench, and it will translocate through the plant and kill any aphid that sucks sap. use a trailing variety of nasurtium, and lay the vines across the cannabis plant's soil surface and near any drain holes.
fungus gnats prefer wheatgrass to cannabis. if you like wheatgrass juice, you can grow the wheatgrass up to harvest size, cut it, and git rid of the rootmass, along with the gnat larvae. you can also treat the rootzone with gnatrol with every watering and use sticky traps. the grass will still be safe to consume, and you won't have to get rid of the rootmass. you can just continue to cut the grass as needed.
