Fungicide

Question: When to spray a Fungicide on my blueberry bushes? I need to use a garden sprayer, with a fungicide chemical, and spray my blueberry bushes for the dreaded "mummyberry" disease. Can someone tell me if it's time to spray now or should I wait till later in the spring? Also, when I do spray, does it matter if it rains within 24 hours?

Answer: To rid of blueberry fungus, spray on the onset of the first warm spell where the temperature is above 60 degrees for 2 days or more. Blueberry fungus doenst grow until that temp is reached. Leaves of no leaves use that 2 day rule on fungus control. Spray at least 2 to 3 applications with the onset of warm weather, once the strong rays of the sun take over in late May fungus pretty much stops the growth process.

Question: When I use fungicide, how long before the black, brown spots on the leaves of my orchid plant disappear? Is there any natural product I can use in place of fungicide and how do I use it?

Answer: 4 teaspoons baking soda 1 teaspoon dishwashing detergent to 1 gallon water. Use when high humidity present or when brown spot or fungus appear. Sorry but spots are not going to disappear, fungicide is a deterent, not a cure.

Question: How do I know if the fungicide I put on my saint austine was effective? I have put two different fungicides on my saint austine grass, but I can't tell if they were effective. Unfortuntately the first round did not halt the progress and it spread to a good portion of my yard. I sodded the grass in the early spring and it looked great up until August. The nights have dropped below 70 F and I can't tell if the second treating of fungicide worked because the grass stopped growing.

Answer: Your right!..... You won't be able to tell unless you can clearly see that the new growth is not infected. Without new growth, it's nearly impossible to tell. The big question however, is what disease or fungus are you trying to control? And, what product are you using to do so?... ...Billy Ray

Question: My plant has Powdery Mildew. If I spray fungicide on it, will it affect the plants surrounding it? Will it, if I do spray fungicide, affect the other plants, or will the powdery mildew spread to my other plants?

Answer: Better to spray on surrounding plants also to avoid further infections /near future.

Question: Liriope crown rot is affecting many of my plants.Is there a fungicide that will help? I have nearly 75 giant liriope plants that boarder my foundation plantings in our front yard. They have been struggling with crown rot most of the summer. I have read all that i can find about what causes this problem, but no ideas or hope that i can save these plants. Has anyone used any fungicide that has helped with this disease? Not all of the plants are infected,and none of them have died yet. I am picking off the affected leaves and removing them from the area by throwing them in plastic bags in the garbage.Any suggestions?

Answer: My boss (Nursery owner) swears by the use of LIME - she pelts the affected plants with the powder, leaves it on the plant for a few hours in the cooler part of the day, then squirts the lime off with water, making sure she get all the lime off. She treats many plants for rust, mealy bug, just about anything and it works!!

Question: how long do i have to wait to apply fungicide on newly planted sod? i planted sod a week and a half ago and its starting to get take all patch fungus, would it be ok to apply fungicide now or i have to wait longer, plus when can i apply fertilizer?

Answer: After a week and a half, your sod, if it was of a good quality, shouldn't have fungus disease issues. You may be in for a refund. I'd check back with the nursery or garden center where you bought your sod. It could have had this problem before you purchased it, and is now showing results of a fungus disease. One other thought--- do you know if your base soil has any fungus diseases? A soil test will help. You should take a sod sample to a good garden center or your county extension agent (USA). Another option is to have a lawn service company take a look at your sod. Depending on the size of the area and the investment you've put in, I would take this step first before applying fungicide or fertlizers-you need to identify the disease first before treating it.

Question: What spreader setting do I use to apply a lawn fungicide? I have a scotts EZ 3000 rotary spreader and I have 5lb bag of a lawn fungicide that I need to apply. The bag says it covers 5000 square feet which is approximately what I have. Does anyone know what I should set my spreader to?

Answer: Typically, if you look on the back of a "Scott's" Fungicide product, it will tell you the setting for any Scotts spreader. It should be around 4 or 5. It's 1 lb/1000 you are trying to apply. Good Luck!

Question: What ecological consequences would occur if humans, using a new and deadly fungicide, destroyed all fungi of E? What ecological consequences would occur if humans, using a new and deadly fungicide, destroyed all fungi of Earth?

Answer: Well Lulu, fungi is very important. It is vital for the making of penicillin (antibiotic) , essential for many fermentation processes like bread, wine and alcohol making, used to make many chemical products like anesthetics, birth control pills and meat tenderizer, moulds are fungi and rusts are caused by fungi and it causes food to spoil, among other things. Could you imagine life without such things as medicine, birth control pills, bread and alcohol? Even in A.C and A.D times, even since the Roman and Greek times there was bread and wine. So I think human existence as we know it would definitely change in a negative way. The death rate would increase drastically since penicillin which is used to treat bacterial infections would no longer be available. Also if anaestetics were no longer available, I would imagine that surgeries would be more painful since anaestetics are used to cause loss of sensation and are used to put people entering surgeries to sleep. I hope this helps.

Question: My summer squash plant has downy mildew can I use a sulpher fungicide to save it? Will the sulphur poison the actual squash? what fungicide should i use if i should not use sulphur?

Answer: Powdery mildew is a fungus that looks like light-colored powder on a plant's leaves. Different powdery mildew fungi attack different plants, but the treatment for these fungi is the same. If powdery mildew is not treated, the plant could eventually die. Cause and Symptoms 1. Powdery mildew usually starts with small round, white or grayish powdery spots that quickly expand. Powdery mildew does not like full sun or high heat and appears on plants that are in shade when the temperatures are between 68 and 77 degrees F, with a relatively high humidity. Symptoms generally appear late in the growing season when the temperatures become cooler and humidity is high. Plants that are close together in shaded areas are particularly susceptible. Powdery mildew injures a plant by depleting nutrients and causing distorted leaves and buds, leaf drop and a decline in the plant's vigor and growth. Treatment 2. At the early stage, spots of powdery mildew may be removed by cleaning the leaves. Large areas require fungicide spray. Many sprays are available, but not all are effective on every plant type. Carefully read the label to make sure the fungicide will work on your particular type of infected plant. Sulphur-based sprays are the most effective fungicide sprays for powdery mildew. Because these sprays can cause injury to some plants, read the label thoroughly before using. You can make your own sulphur spray by mixing several crushed cloves of garlic with water. As an alternative to sulphur, copper sprays can be quite effective. Whatever spray you use, begin as soon as you notice the problem and continue throughout the remaining growing season. Because the powdery mildew can survive in unlikely circumstances, it's important to remove all the leaves and debris around infected plants and dispose of it responsibly. Do not add to compost.

Question: Why might a crop develop a severe phosphate deficiency after being sprayed with a fungicide? Why might a crop develop a severe phosphate deficiency after being sprayed with a fungicide?

Answer: it may bind or precipitate phosphorous making it unavailable to the plant or block uptake (depends on what forms of P exist in that soil and the fungicide used).

Question: How long is it before i can harvest and eat a vegetable that has had fungicide applied to it? I applied fungicide to my zucchini plants while the fruit was still growing and i want to know at what time will it be safe to harvest and eat them.

Answer: Usually you can harvest your plants about 2 weeks after being sprayed if they are ready to be harvested. Read the label of the fungicide chemical that you put on it. It should tell ya. One reason that people end up with fungi on their squash plants is because they use a sprinkler to water them. This puts water on top of the plant that then turns to fungi. if you water with a hose running under the leaves you won't get the fungi.

Question: How to use Garden Safe Fungicide? I bought this brand of fungicide at Wal-Mart but am confused about how to use it. It says to apply it on a 7 to 14 day schedule until the potential for disease development is no longer present. Does that mean that I spray it on the plant every day for 7 to 14 days, or spray it once on the plant every 7 to 14 days? I'm confused, please help!

Answer: The latter statement you made is right. It means that you can apply it on a 7-14 day interval. In most instances, after these two applications the fungicide will control any further threat of infection but this depends on the severity of the disease or fungus. Do another application anywhere from 7-14 days after the first. Be warned however, that a fungicide will not "reverse" the already damaged leaves, it will only prevent any further infection of the non-infected foliage. The damaged leaves will more than likely prematurely yellow and then drop. "Always" follow the labels instructions regarding the mixing strength and time to apply. Hope this answers your question... ...$Billy Ray$

Question: Fungicide - How long should I wait before eatinng vegetables that I've used Fungicide on? I noticed a mildew-like fungus growing on some garden tomatoes that I have. I used Acrobat MZ to stop the fungus about a week ago. The tomatoes are almost ready for consumption. How long should I wait before I'm able to eat the tomatoes?

Answer: About two weeks since you applied it. Every pesticide has a recommended PHI (pre harvest interval). "Acrobat MZ may be applied by ground or air at a rate of 2.25 lb/A up to a maximum of 5 times per season. There is a 14 day PHI." http://www.ext.nodak.edu/extnews/pestqtrly/pq15-3w3.htm

Answer: Rose Pride By Ortho

Question: How can i test the fungicide on the fungi? How to make sure the fungi not contaminate with other fungi? As i know,there are two methods that we can use:-poison technique and leaching technique.So,how we want to apply these methods and to know which method is better to control the fungi?

Answer: The best way to test the fungicide is to use it. If the fungal population is reduced, the fungicide is effective. If you apply both methods and also maintain some fungi that you don't try to kill at all (a "control group"), you can compare your results. In order to determine if other fungi are present, you could try using a fungicide that is not expected to be harmful to other fungi (This would leave any invasive fungi unaffected as the target fungus dies out, leaving them more easily detected.), or you could monitor the habitat for chemical changes resulting from biological products not produced by the target fungus (implying that another organism is present).
