    Organic

    Does anyone know any good organic pesticides, insecticides, etc 

     

    I already use a product called organicide and it does not fully do the job, looking for some thing a little stronger

    try this site for ideas  http://www.organiccatalogue.com/

    another good way is soapy water, depending on the bug you want to deter, then companion growing is a good idea; eg marigoldswith your tomatoes / beans deters black & white fly, even in the greenhouse.

    Re: Organic pesticide

    It is easy to make your own white oil from vegetable oil and liquid soap. Prepare the concentrate using the proportions below. Store in a suitable container. Label the container, making sure to include the dilution rate on the label for quick reference.

    Ingredients
    1/2litre of vegetable oil (any brand)
    1/2cup Sunlight dish washing liquid


    Dilution
    Dilute the above mix by placing 1 tablespoon into a litre of water. Mix well and spray thoroughly over both sides of the foliage and onto the offending pest.

    The contents of the stored concentrate will separate over time. Simply ensure that the concentrate is well mixed each time before you attempt to dilute it for use. Spray as often as required.


    Use
    Oil based sprays are useful in controlling a wide range of insect pests and mites. In most cases the oil covers the body of the insect or mite, causing it to suffocate. Scale, aphids, pimple psyllids, mites and even young grasshoppers can be killed by contact with the oil. In the case of citrus leaf miner, the shiny oil coating on the leaves repels the moth responsible for laying eggs on the new leaves of citrus plants. These eggs quickly hatch into larvae that tunnel between the upper and lower surfaces of the leaves causing the characteristic silvery trails and distortion of the leaves.


    Precautions
    Always following the directions as to the dilution rate as oil based sprays can burn if applied in strong concentrations. Do not apply in hot weather. Do not use on plants with hairy leaves, ferns or palms and reduce to half strength on native plants with fine foliage (eg leptospermums or tea trees). These precautions apply to home made preparations as well as commercially available oil sprays. Commercially available preparations are generally petroleum-based products and their use is not permitted under organic certification.

     I also a add a little garlic to give it an extra kick

    Organic Gardening

    Horticultural oil in the appropriate mixture with water, works as well, if not better than just vegetable oil, in my experience. Organic gardening is a lot of work, any problem plants with pests will have to be treated repeatedly, over and over and over and over, until the life cycle of that pest/disease, what ever the threat is, disappears or weakens enough that the plant/fruit will be able to survive without too much damage.Enviromental conditions and the health of the plants really is the key factor of organic gardening pest solutions. Weakened  plants have a higher risk of  pest problems, and when possible should be removed to lessen the threat those nearby. Be cautious when using any mixtures with oils during bright sunlight, or high temperatures! The oil definitely will cover and smother the pests, and will do the same to the leaves, cutting off respiration and encasing the leaf like seran wrap, the heat will cause a closed greenhouse effect ( imagine being in a ziploc bag in 90/100 degrees) while the light is reacting with the oil like a magnifying glass and increasing the temperature. It can cause serious damage to the leaf tissue. I treat plants early morning/late evening or on overcast days then hose off spray in 2-3 hours.I'm suprised the above mentioned site said not to use on palms, there is a serious infestation of oriental scale threatening sago palms in Florida,( sagos are not truly palms but simular) and this is the one method that seems to work, I've been using it for years! OH! Tea tree oil is an excellent repellant for small sucking insects, add couple drops to spray bottle with hort. oil mixture and shake, use as described above.

    Bacillus thringiensis,
    Bordeaux mixture,
    Insecticidal soap,
    Plant oils,
    Pyethrum,
    Derris
    sulphur

    Not sure what you have available in your region but all the above is approved by the organic society in UK, hope this helps.

    Re: Organic

    two i didn't see listed, neem oil, or it's extract, azadirachtin are both approved... also spinosyn A/D is OMRI certified.

    neem has the benefit of being an oil, and having growth retarding properties.

    spinosyn is sort of a total knock out.

    pest out is a decent spray as well, you may have to search around to find it but its a combo of a bunch of essential oils... check phytotoxicity on a small portion of any plants you spray, but if you're using organicide i doubt you'll have problems with any of these.

    and as jay said, pyrethrum makes a decent broad spectrum killer, only problems is that some insects develop an immunity to it, and if it is a truly organic pyrethrum (not bifetrhin, permethrin, etc...) then it will break down in the sun very quickly.

    Re: Organic

    I'm using mostly DE and BT with occasional pyrethrum spray.
