Milky spore granular11/11/2023 ![]() Neither the Milky Spore powder nor the Milky Spore Spreader mix should be mixed with water and sprayed.ħ. Can I mix the Spore with water and spray it? Milky Spore does not affect pets, beneficial insects, fish, bees, birds, other animals, plants, or man. It may be used in gardens, around pools and wells. Yes, Milky Spore is harmless to food crops. Milky Spore is safe for the environment and is not affected by pesticides, fungicides or herbicides. Will fertilizer or chemical pesticides that have dursban and diazinon in them affect Spore?ĭursban and diazinon have been banned by the EPA as toxic to the environment. Heavy rain may wash away newly applied Spore dust necessitating retreatment.ģ. No, Milky Spore is not affected by freezing or other adverse environmental conditions. Will freezing ruin the Spore? What about heavy rain? Once established in a lawn, Milky Spore has been known to last 15 to 20 years.Ģ. In colder areas like New England, three to five years. In warm climates good control can occur in one to three years. Once grubs are infected they will multiply the Spore by several billion times and spread it further. Milky Spore begins working as soon as it is applied as long as grubs are feeding. How fast does the Spore work and how long does it last? The recommended lawn grass in Maryland is turf-type tall fescue, and those lawns aren't terribly bothered by grubs, and likely used less often for reproduction. You might aim your control around the favored feeding sites.MILKY SPORE - Frequently Asked Questions:ġ. Your 'trap crop' idea may not work depending on the grass varieties growing. They tend to bring more jb to your yard than you would have otherwise. However, the newer Grub-Ex products are effective with reduced toxicity than previously. That poor efficacy and high cost are why we don't recommend it. The original research results of using milky spore were not able to be replicated by others. The populations can vary greatly from year to year based primarily on how dry the ground is when they seek to lay eggs the year before. In many areas Japanese Beetle populations were not high this year. I live in Clarksburg, so maybe the area's ruralness and development practices have caused the huge population (up until this year). beetles that hatched from neighboring areas would find their way to my trees that the j. Even if my milky spore application killed many larvae, surely j. I don't know if some neighborhood activity is the cause of the drastic decline. Probably due to some other reason, I've only seen two or so j beetles this year! Some of that is likely due to changes in my attentiveness / habits. I bring this up partly to see if this is a reasonable neighborhood solution - use a decoy crop (such as chinese elm trees) to attract the j beetles, whose next generation would be killed by milky spore or your currently recommended j beetle grub killer.ģ. I realize that is not the recommended dosage. ![]() I have used milky spore in and around that area sporadically (maybe 3 times) over the last few (maybe 10) years. ![]() ![]() If I could have milky spore kill a very large percentage of their grubs, I would be doing myself and neigborhood a long-term favor. I assume the fertilized female ones I don't catch fall from the trees to the ground to lay their eggs. I manually caught (and eventually killed and buried deep) hundreds of the beetles daily. The last few years, thousands of j beetles feed and mate on them each year a few of them feed on some nearby pears, blackberries, and a crepe myrtle. I have more than 20 chinese elm trees that I've tried to trim to be merely a huge hedge along a 70 ft. You mention that "Grub control is usually not a solution to lawn problems." But remember that I want to control the japanese beetles via destroying their grubs rather than merely trying to improve the lawn. I'll guess you mean "batch of originally produced product".Ģ. I am not sure of the meaning of "population" in your "not as effective as the original population had been". I accept (but not totally) that milky spore is no longer recommend it, but I have further question(s) / comment(s).ġ. ![]()
