Lecture 13 group 3 Flashcards
1
Q
group 3 inhibits:
A
cell division (miotic inhibitors)
2
Q
group three - Dinitroanilines (DNA’s) examples
A
‘the yellows’
Trifulralin
Ethafluralin
3
Q
do group 3 escaped weeds show any injury?
A
no, appear as normal –> successful control = no germination
4
Q
group 3 - pre or post emergence?
A
pre- emergent soil applied
5
Q
group 3 MOA
A
results in cessation of mitosis and meristematic elongation
6
Q
group 3 target site
A
tubulin
7
Q
group 3 selectivity
A
no differential between monocots and dicots
8
Q
group 3 selectivity in monocots
A
selectivity based on structural differences, herbicide placement and seed depth
most sensitive zone in cereals can remain below herbicide treated soil layer
9
Q
is the coleoptile affected by group 3’s DNA
A
coleoptile not sensitive
