We would recommend waiting until the plants have dried after a rain before spraying Sevin Concentrate. The product label also states it is recommended to apply this product in calm weather when rain is not predicted for the next 24 hours.
For best results, you should apply Sevin Concentrate at least 24 hours before you are expecting any rain. After that point, it will be rainfast and you will not need to reapply.
Sevin Concentrate does state it should not be applied to trees larger than 10 feet tall; this is possibly because doing so would not apply an adequent amount of product to the trunk to be effective in killing insects that contact it. When treating for bark beetles, it is recommended to spray up to 15 feet high since generally they do not go much higher than that. You can use a product like Permethrin SFR to do so. Unfortunately, once the borers have already infested the tree there are not any viable treatment options as they would be protected from sprays. In cases of infestation the general recommendation is simply to protect the surrounding trees with preventative sprays with a product labeled for such a use. Infested trees will need to be trimmed and/or completely removed.
You will mix 1.5 ounces of Sevin Concentrate per gallon of water for grasshoppers.
Even though Sevin Insecticide Granules and Sevin Concentrate have the same active ingredients, they have different formulations. Because they have different formulations, they have separate Product Labels that have separate use instructions. For more detailed information as to why the Sevin Insecticide Granules can be used on lawns, where the Sevin Concentrate is limited to vegetables, fruit, and ornamentals please contact the manufacture, GardenTech at 866-945-5033.
Sevin Concentrate can be applied around landscaped areas and flowers. We recommend that you test a small area first and do not treat in the heat of the day to avoid burn/injury.
Per the product label, Sevin Concentrate can be applied "as needed," but cannot exceed a certain number of applications per year. The exact number of applications will depend on what type(s) of plants are being treated and can be found on the product label.
Unfortunately the Sevin Concentrate is not labeled for hookworms. There is not a product on the market that is labeled or recommended for hookworms. While some insecticides that are labeled for turf or lawn infesting insect may work, there has not been enough research to add hookworms to the product labels. We recommend thatif you have pets, they be moved out of the contaminated area for at least 6 weeks (during warm spring/summer months, longer during cool winter/fall months) and all feces be removed. Keeping the animals out of the contaminated area for at least 6 weeks should help control the infestation pattern. It is also important to remove feces from the new latrine area to avoid another infestation. Another option is to remove the contaminated soil and replace if you cannot keep out for 1 year.
Sevin Concentrate disposal varies from place to place. The manufacturer recommends to contact the local sanitation dept for instruction.
Sevin Concentrate is safe for cats and other animals when used as directed on the product label. Pets should be kept out of the area until dry, typically a few hours is best.
Once Sevin Concentrate has dried completely, it is sale for people and pets to return to treated areas. If the dog ingests grass treated with the product after it has completely dired, it shouldn't pose any harm to the dog.
