## Description

Nemasys Leatherjacket Killer Nematodes Treats 100sq.m + Nematode Applicator : desertcart.co.uk: Garden

Review: Effective - Worked perfectly
Review: Best applicator for nematodes - I tried another more expensive applicator specifically for nematodes before this.. this one is far better. This one is made a bit cheaply so parts of the plastic have began to come apart for me after around 20 hours of use. I also find this sprayer useful for applying liquid feeds - they're no so easy to measure the water mix precisely but it works well enough for me. The nematodes do seem to have had an effect. The brown/bare patches in my lawn this year were not down to grubs but just due to the drought and were more minor than previous years thanks to a few applications of nematodes.

## Features

- Kills leatherjackets in lawns safely and effectively.
- Apply when grubs are present, soil is moist and temps above 10C.
- Best applied after crane flies (daddy long legs) have emerged and are laying fresh eggs in the grass. This normally happens in September but may be earlier this year following the mild autumn.Grass cutting, fertiliser application and weed control can carry on as normal
- THIS IS A PERISHABLE PRODUCT WITH A 2 WEEK EXPIRY DATE. PLEASE ORDER WHEN YOU WANT TO APPLY . Apply by watering can or hose end feeder. Pack will treat 100sqm
- Complete with Nematode Applicator for easy application.
- Connect to your garden hose for seamless application with our convenient applicator.

### ⭐⭐⭐⭐⭐ Best applicator for nematodes
*by P***L on 25 November 2022*

### ⭐⭐⭐⭐ Ideas the job and does it easily.
*by C***P on 30 May 2021*

I have to treat my lawn in spring and autumn for leatherjackets and this product together with the sprayer makes it much easier than filling endless watering cans. The sprayer will be great for lawn feed too. A good product, just dropped one star as I thought the two together were a bit overpriced. Does the job though which is the main thing.
