If you don't want to share your outdoorbcrop with the gazillion different bugs, bacteria or fungus you must adopt an IPM: Integrated Pest Management System.
From the web:
"Integrated Pest Management (IPM) is a science-based strategy that combines various methods to identify, manage, and prevent pests and their damage. IPM emphasizes long-term, ecosystem-based solutions that minimize environmental and human health risks. Key aspects of IPM include:
Monitoring: IPM uses monitoring to determine if and when pesticides are needed.
Targeted treatments: Treatments aim to remove only the target pest.
Multiple methods: IPM combines biological control, habitat manipulation, and other techniques.
Pesticides as a last resort: Pesticides are only used after monitoring indicates they are necessary.
Reduced risk: IPM aims to minimize risks to human health, the environment, and non-target organisms."
Personally using an IPM I have taken my game to another level but what is SAFE to use on a plant that most of us will be smoking?
I use:
Neem oil
Capt. Jack's Dead Bug
Bt
Southern Ag Bio fungicide
Beneficial insects/nematodes
Neem oil has gotten a bad rap from those who have never used it but read or heard it will impart a taste to your weed and could give you lipid pneumonia from smoking the oil.
Neem oil has a half life of 1.5 days. Once sprayed it will only work on most pests, the main ones being aphids and spider mites when it coats them as you're spraying. In other words any of the aforementioned pests that land on your plants after spraying will not be effected. On the other hand it will stop bud worms from eating IF they eat a portion of a plant that has an active dose but again, only for a short time of 3-5 days.
Morning dew and rain will wash off most if not all of the treatment and the plant will need to be sprayed again before the standard time of 4+/- days of protection wears off.
Neem leaves a bad taste? I guess if you sprayed the plant a day or two before harvest and didn't spray the plant down well with water then I bet it would, but if you use
neem oil up to 5-6 weeks into flower and then switch to Capt. Jack's for the final couple weeks and wash the plant well with hose and gentel spray there won't be much if any residue.
Just for fun I sprayed a plant with
neem oil a month ago 3 days before harvest. I washed the plant the morning of harvest with the hose, allowed it to dry and cut her down. 10 days later I rolled one up and there was no hint of neem, smell or taste. Now on the safe side I used this plant to make coconut oil and that oil I put in a brownie mix last night and absolutely no neem smell or taste. But if you're allergic to neem DO NOT USE IT. Otherwise it has become my go too all around insecticide, fungicide and antibacterial spray.
Capt. Jack's Dead Bug is a biological insecticide similar to Bt. While there isn't much research on smoking cannabis after use there are instructions on tobacco: you can spray tobacco up to
six times per growing season, with reapplication every
10 days if needed. It is crucial to follow the specific instructions on the product label for the correct dosage and for the pre-harvest interval (PHI) of at least 7 days before harvesting, and thoroughly wash all edibles before consuming.
I'll use Capt Jack's the last few weeks of flower but only if needed and I keep to only using 3 times.
Bt is another biological insecticide: Biological insecticides are pest control substances derived from naturally occurring organisms like bacteria, viruses, and fungi. These "biopesticides" are often highly selective, targeting specific pests while being safer for humans, beneficial insects, and the environment compared to many synthetic chemicals. Common examples include
Bacillus thuringiensis (Bt), which produces toxins that are harmful when ingested by insects, and
beneficial nematodes, which can penetrate and kill pests.
Bacillus thuringiensis (Bt): A soil bacterium used to control pests like caterpillars and beetle larvae.
When a bud worm (moth larvae) eats a section of plant matter that was sprayed within a few days with Bt the worm will stop eating and die. I’ve pulled dying worms off plants.
Bio Fungicides: Fungi: Microorganisms like Beauveria bassiana and Metarhizium anisopliae that grow on and infect insects.
I use this fungicide the last couple weeks of flower in place of
neem oil. It does not work as well as neem but is an option if needed. Again, before harvest WASH off your plants.
The common theme here is to WASH your plant(s) before or after harvest. I’ve been doing that for years just to remove dirt and debris. Here's a great idea if you only harvest a plant or two:
Insect helpers like lady bugs lacewing, wasps, nematodes, etc are good natural helpers. Creating the conditions to naturally increase their numbers is beneficial. I’ve purchased lady bugs and lacewings in the past and unfortunately once their food supply is diminished they wonder off for greener pastures. Lacewings seem to stay a bit longer and produce more visible offspring which helps establish them in you yard.
When to apply these products? NEVER spray plants in the heat of the day. The best time to spray is either at sun down or an hour before sun up. This way beneficial insects as well as honey bees will not be effected and the plants won't be burned.
If you've never grown outdoors with all the bugs and insidious fungi and bacteria your opinion of the use of these natural OMRI rated products is worthless. Sorry, Just the way it is. If you want to succeed in outdoor growing you better take heed to IPM or all your hard work and time spent will be wasted on the bugs
