We have not heard of this happening with the Sevin Concentrate but would advise you to contact the manufacturer directly for advise. GardenTech can be reached at 866-945-5033.
Yes, Sevin Concentrate is labeled for springtails.
Sevin Concentrate is applied at 4 oz per gallon of water and applied with a Hand Pump or Hose-End Sprayer for chafers.
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 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 3.0 fl. oz. of Sevin Concentrate per gallon of water for apple trees. Be sure to spray upper and lower leaf surfaces and between fruit clusters and on small limbs and trunks to the point of runoff where pests appear. Repeat applications as necessary up to a total of eight times per year for tree fruits or five times per year for small fruits, but not more often than once every seven days. NOTE: To avoid undesired apple thinning delay use until at least 30 days after full bloom.
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.
Yes, Sevin Concentrate is labeled to kill sawflies. We would also recommend our Flies Be Gone Fly Trap for long term control. Flies Be Gone traps appeal strongly to a flies' natural instincts. It provides them with food and a warm place to lay eggs. Once inside the trap, they cannot escape. Flies Be Gone bait is especially appealing to female flies. Up to 85% of flies caught are female, which helps decrease the next generation of flies.
Sevin Concentrate is not for use on turf, only for use on ornamentals and listed edibles for adult Japanese Beetles. For grub control in lawns and around ornamental plants, Dominion 2L (liquid) and Merit G (granule) are our most popular products. Tempo SC Ultra can be used for the adult beetles on ornamental plants. We have more great information and tips in our White Grub Guide here.
Sevin Concentrate would be good to apply before pests are an issue or while they are active in the area, it has a residual of up to 3 months.
Sevin Concentrate will kill the adult termites that are sprayed with the product. It will not replace a termite soil treatment around the perimeter of the structure. There are products that you can use to treat in the tree directly. Just keep in mind that termites are there because the tree is already dead or dying, so be sure to take down dead trees before they cause other damage. You could use Alpine Ant and Termite Foam to spot treat exactly where the galleries are in the tree. This product has a foaming agent to help coat the inside of any voids. Alternatively, you could use Dominion 2L as a spray, again treating inside the galleries directly. We would recommend using a termiticide like Taurus SC against the foundation in a trench or drilled holes (where there is concrete). You can find more information on doing a complete treatment for termites in our Termite Control Guide.
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.
It is recommended to apply Sevin Concentrate when you are not expecting any rain for 24 hours.
Sevin Concentrate should be fine to spray on dichondra, just be sure not to apply during high temperatures.
You will mix 1.5 ounces of Sevin Concentrate per gallon of water for grasshoppers.
