looks like grasshoppers have you noticed any jumping around? they chewed the shit out of my plants and thats exactly what mine looked like well ganja guerrilla told me to "Steep 4 garlic cloves in 1 litre of boiled water for 24 hours. Strain. Do not dilute add 5-8 drops of dishsoap. Spray on plants, no more than twice a week" i am waiting for my garlic to steep right now but i Suggest you do the same
Holy crap! They have been having a feast on your leaves. I don't know if it is grasshoppers or caterpillars but you've got to stop them hard. I haven't had to use pesticides on my MJ this year, but I've been using Rotenone and Pyrethrin spray on my vegetables for years and have not experienced any adverse effects...except maybe that third nipple in the middle of my chest...j/k If you have a few weeks before harvest and you're growing outside, chances are that all of the spay will be washed off and you'll never notice. I does a good job of controlling the munching meanies...not as good as DDT but it will kill. http://www.planetnatural.com/site/rotenone-pyrethrin.html Good luck
If you want an all natural pesticide, buy some cigerette rolling tobacco, soak it in some water for a couple days, and spray it on your plants.
Don't spray "Nicotina" on any thing you are going to put in your body.... Tobacco is the Most Radioactive plant known to man..... it stores heavy metals in its leaves.....don't spray it on the ladies Use the Garlic spray ...or Safers Ya' got Hoppers either Grass or the lil' leaf hoppers
I don't think the damage is caused my leafhoppers... What do leafhoppers eat? All feed on plant sap. Leafhopper species feed on a wide variety of vascular plant species, including grasses, sedges, broad-leafed woody and herbaceous plants of many families, and conifers. At least one leafhopper species can usually be found feeding on the each of the dominant plant species in practically every terrestrial ecosystem. Frequently several leafhopper species can be found coexisting on the same plant.
Pyrethrum is by far the most effective, and most used of the insecticides. It is extracted from the flowers of the pyrethrum chrysanthemum from Africa. it is hard to make at home and can be found commercially sold at retail nurseries(there are many types available. Being an insecticide with a wide array of uses, pyrethrum is very toxic to most insects, even those that are beneficial. If the insect doesn't receive a large enough quantity, it may revive, so pyrethrum is usually combined with rotenone or ryania to ensure effectiveness. Pyrethrum should be used to spot spray only heavily infested plants. It is non-toxic to animals and humans, and is very effective when applied to your garden manually. Nicotine can be a very effective method of pest control as well. It is naturally derived, however, it is not usually used in organic gardens due to its toxicity. Nicotine can be deadly to most insects and humans, when swallowed in concentrate. This poisonous compound, affects the neuromuscular system causing insects to go into convulsions and die.
which product should i use of safers? I have "end all" by safers is this good enough? should i use something stronger?
The insecticide you use (especially when using organic, "safe" products) depends on the pest you're trying to control. Example: Safer Soap and NEEM Oil controls Adelgids, Aphids, Earwigs, Grasshoppers, Lace Bugs, Leafhoppers, Mealybugs, Plant Bugs, Psyllids, Sawfly Larvae, Scales, Spidermites, Tent Caterpillars, Thrips, Whitefly (whiteflies) and Wooly Aphids. I read where BTK (Bacillus thuringiensis) insecticides are effective on munching critters like caterpillars but I don't have any experience with it. I tend to go with the strongest insecticide that I feel comfortable consuming in my case [SIZE=+2]Rotenone/Pyrethrin based sprays. [/SIZE]
have you considered just letting this ride? Thats a strong, mature plant. It can hanldle it. If I had to choose betwee strong insecticides or just letting the plant tough it out, I would let the plant go. They never cease to amaze me with what they can endure.
If you want to buy something instead of making home brew, I use Fox Farms Don't Bug Me and it works well. Says it works for crickets if that's indeed you problem.
