NEMATICIDEFOSTHIAZATE
Contact nematicide
Fosthiazate is a nematicide discovered and developed by ISK.
Fosthiazate provides a good and stable control of cyst, root-knot,
root lesion and free-living nematodes in a wide range of crops
such as potatoes, bananas, tomatoes, and other vegetables.
The control activities of fosthiazate remain unaffected by soil
type, soil pH and soil temperature.
Since the early 1990’s, ISK has commercialized fosthiazate inmultiple countries.

Application

Mode of Action

Broadcast and soil incorporation to control nematodes (Meloidogynespp., Heterodera spp. and Pratylenchus spp.), aphids, mites, thrips, etc
in vegetables, potatoes, tomatoes and bananas, etc. Applied mainly at
1.5-3.0 kg a.i./ha.

Inhibition of acetylcholine esterase in nematodes and other pests.
Its excellent systemic action also provides high performance against
nematodes and foliar insect pests.
Acts against motile larval stages of nematodes in the soil and prevents
invasion to roots of crops.
