    Q
    Is Bonide Liquid Copper Fungicide Concentrate safe to use for a dichondra lawn that has turned brown during a very hot Phoenix, AZ, summer?
    not sure if it has a fungus or watering and 116 degree weather but my dichondra is turning brown rapidly in patches. Can I use Copper Fungicide to help it come back? Bonide brand
    A

    If it is that hot, then your dichondra may just be under heat stress. A fungicide like Bonide Liquid Copper may not help when temperatures are that hot. Dichondra does not respond well to over-watering or watering that is too frequent, so be sure you are watering less often and more deeply rather than every few days. If you have dichondra rust, then you can use Propiconazole 14.3 to treat this disease, but try to apply in the morning or evening when temperatures are cooler.

    Q
    Can I use Bonide Liquid Copper Fungicide Concentrate for hellebores in cool temperatures?
    My hellebores have black spot. how warm does it ned to be for copper spray to be effective
    A

    Per the product labelBonide Liquid Copper Fungicide Concentrate should not be used on roses in cool damp conditions (under 60 degrees F) due to concerns of phytotoxicity. We recommend following this recommendation for similar flowers as well such as your hellebores.

    Like most products, Bonide Liquid Copper Fungicide Concentrate should not be used in temperatures over 85 degrees. We usually recommend that you spray early in the morning or in the evening when the temperatures are usually cooler and the product will have time to dry before temperatures reach 85 or above. Spraying in the heat of the day will cause the foliage to burn.

    Q
    Too late to apply Bonide Liquid Copper Fungicide Concentrate in November?
    Is it too late to apply Bonide Liquid Copper Fungicide now to my apple , peach and pears trees , I am in zone 5, my fruit trees have dropped their leaves but we have already had a frost and temps have already been in the high 20s?
    A

    While it may be a bit late to apply Bonide Liquid Copper Fungicide Concentrate on peach trees, you may still be able to make a late fall application to apple and pear trees since both ripen between late summer and late fall. November is usually late for an application, especially if you're already dealing with freezing temps.

    Q
    Can I spray my fruit trees with Bonide Liquid Copper Fungicide Concentrate?
    I have a mixed orchard of pears/peaches/cherries and apples. Some buds are silver tip, some are swelling, some are half inch green, and some are tight clusters.
    A

    The Bonide Liquid Copper Fungicide Product Label States- Apples & Pears: Do  not exceed one application during the fall, late dormant period. Do not exceed one application between silver tip and green tip growth stages. May cause russeting of susceptible apple varieties. Repeat application every 7-10 days during bloom and growing season if needed. 
    For Cherry, Peach,etc: For bacterial canker, apply as a dormant spray as buds begin to swell, repeating at the bud burst stage, and weekly thereafter as needed, up to six sprays. In the fall spray again at 10 and 80% leaf fall. For brown rot, blossom blight, apply full cover spray at delayed dormant (but swell), popcorn, full bloom, and petal fall stages. Repeat application every 7-10 days if needed.
