Mode of action

Wriar™ is a broad-spectrum insecticide which kills insects upon contact by affecting the normal function of the nervous system. Wriar™ affects the nervous system by inhibiting the breakdown of acetylcholine (ACh), a neurotransmitter. When insects are exposed, Wriar™ binds to the active site of the cholinesterase (ChE) enzyme, which prevents breakdown of ACh in the synaptic cleft.

Dose & application

Wriar™ is broad-spectrum, chlorinated organophosphate (OP) insecticide, acaricide and nematicide.

Why it pays

A pest caught at threshold costs one spray. The same pest left for another fortnight costs three sprays and a share of the crop, because by then it is feeding inside the stem or the boll where nothing reaches it. The value of this product is mostly in the timing, and the timing is free.

Field tips

Cover the underside of the leaf. Most sucking pests sit there, and a spray aimed at the top of the canopy never touches them.

Do not raise the rate because the last spray disappointed. A poor result is far more often bad coverage, the wrong growth stage, or rain within two hours than it is a rate that was too low. Raising the rate mostly builds resistance.

Change chemical group between sprays rather than repeating the same one. A pest sprayed with the same molecule three times in a season is being trained to survive it.

Safety

Wear gloves, a mask and full sleeves. Spray in the cool morning or evening, never into the wind, and wash thoroughly afterwards. Keep children and livestock out of a sprayed field until the spray has dried. Most insecticides kill bees, so do not spray a flowering crop during the day. Never re-use an empty container.
