CHAFER/07
For the biological control of chafer grubs in lawns.
HOW SPORTNEM-H WORKS
After application, the nematodes actively search for their prey and penetrate them. The nematodes feed on the contents of the prey, excreting specific bacteria from their digestive tracts as they do so. These bacteria convert host tissue into products that the nematodes can easily ingest. The larvae die within a few days. Once the insect larva has been entirely eaten, the nematodes crawl out again to prey on other larvae.
APPLICATION
Preparation of the solution
Half an hour before preparing the product, remove the pack from the refrigerator and let it come up to room temperature (20°C)
Break the contents of the sachet (250 million Heterorhabditis bacteriophora) into smaller pieces. Use the entire pack and place the smaller pieces in a bucket containing five litres of water (at 15 to 20°C)
Leave the bucket with the solution to stand for five minutes
Then stir the solution until all the lumps have disappeared before transferring it to the spray tank
Use the spray solution straight away
Application and dosage
Remove all gauze openings of less than 0.3 mm (50 mesh) in order to prevent blockages.
You can use a watering can, backpack spray unit, motorized spraying system, or sprinkler system.
Use as little pressure as possible (max. 20 bar)
Use the contents immediately after preparation.
Apply the solution homogenously over the area to be treated.
Apply the solution late in the evening or early in the morning.
IMPORTANT: Spray the lawn before and after the application of the product with 2-5 litres per m2 and keep the ground moist for a period of two weeks after application.
BEST WORKING CONDITIONS
HANDLING
Biological beneficials have a very short life expectancy and therefore need to be introduced into the crop as soon as possible after receipt. Failure to do so can have a negative impact on their quality. In case you do need to store Sportnem-H, please follow the instructions below. Koppert Biological Systems is not liable for any loss of quality if the product is stored longer and/or under different conditions than recommended.
