Agricote Grass

  • AGRICOTE Grass seed treatment contains insecticide and fungicide, to help prevent damage from Argentine stem weevil (ASW), black beetle, grass grub and damping off diseases.
  • AGRICOTE Grass is recommended where pests are a problem, because endophyte provides only limited protection for seedlings (as opposed to mature plants).

 

ASW control

Adult ASW can be a major pest, particularly in grass to grass renewal or autumn sowing in dryland environments (see page 116 for more). In these cases it is important to protect all grasses - annual, Italian, hybrid and perennial ryegrasses, or tall fescue, with seed treatment.
In a trial conducted by AgResearch just emerging Tabu Italian ryegrass seedlings were exposed to adult ASW attack. The results (right) show that AGRICOTE Grass and Poncho gave excellent control of ASW adult attack, significantly better than Gaucho or bare seed.

 

 

 

Black beetle (BB) control

BB can cause significant establishment problems in the upper and coastal North Island, particularly in dry seasons.
In a trial conducted by AgResearch, Tabu Italian ryegrass seedlings were exposed to a high level of pressure from adult BB. The results (right) show all three seed treatments gave excellent control of adult BB attack, significantly better than bare seed.

Grass Grub (GG) control

AGRICOTE Grass provides excellent control of GG. In a trial run by AgResearch, Tabu Italian ryegrass was sown into vials, and an actively feeding large larvae (3rd instar) was placed into vials when seedlings were just emerging, then again 7 days later, and then 14 days later.
The results below show that all three seed treatments gave excellent control of GG larval attack, significantly better than bare seed.

 

 

Fungal pathogens

AGRICOTE Grass contains fungicides that control the fungi responsible for ‘damping off’ (Fusarium and Pythium) which can kill seedling plants through the establishment period.
These fungi are most active in autumn and winter, and attack plant tissue leaving lesions at or below ground level. Newly sown ryegrass seedlings are most susceptible to being killed by damping off because of their small size and vulnerability. This in turn can lead to poor, patchy pasture establishment.

 

Sowing rate

AGRICOTE Grass has no effect on seed weight, therefore, normal sowing rates should be used.

 

Withholding period

42 day stock withholding period applies for new pasture sowings; 21 days when undersowing AGRICOTE Grass into existing pasture.
