Summary of the invention
The present invention seeks to develop the weed killer herbicide in a kind of suitable paddy field.
The propazine chemical name is a 2-chloro-4,6-two (the different third ammonia alkane)-1,3,5, and-triazine, its structural formula:
Its molecular formula: C
9H
16CIN
5
Through test millet propazine (Propazine) there is stronger drug resistance.
The chemical name of symetryne is a 2-formyl-4,9-two (ethylamino)-1,3, and 5 triazines, its structural formula:
Molecular formula: C
5H
15N
5S
Symetryne (Simetryn) has higher activity of weeding, and millet has certain drug resistance to this medicine.
The present invention is two kinds of medicaments be mixed (percentage by weights)
93% propazine raw material 38.80~43.11
97% symetryne raw material 1.89~6.12
Neopelex 5
Inferior solid 20
White carbon black 5
The diatomite surplus
The mixed agent of 50% propazine wetting powder and 5 different proportionings (percentage of effective ingredient) of 25% symetryne wetting powder.

2, with ED
50The co-toxicity coefficient value that value is calculated compares ED
90The co-toxicity coefficient value height that value is calculated.
3, with ED
90When value was calculated, its synergistic effect was relevant with the content of symetryne, and the 1# and the 2# proportioning that is mixed are best to be mixed.
4, from activity of weeding with to the combined factors analyses such as safety of millet, selecting mixed agent 2# is best proportioning, and its proportioning is:
Propazine: symetryne=88.9: 11.1
Advantage of the present invention is remove to mix that to control millet field weed effect remarkable, and every mu of usefulness 100~200 grams are are comprehensively wiped out and treated insect pests and plant diseases effect 84.9%~97.1%, increase herbicidal effect with dose and improve, and it is best that mu restrains effects with 200.The 45%I millet straw kills grass only and has composed, and can efficiently wipe out and treat insect pests and plant diseases monocotyledon weeds such as lady's-grass, green foxtail, can wipe out and treat insect pests and plant diseases broadleaf weeds such as kitchen garden, Amaranthus retroflexus again, and disposable dispenser prevents and treats multiple weeds.
Table 5 45% millet straw is only except that 20 days herbicidal effects after the dispenser of millet field weed
The clean wetting powder of table 6 45% millet straw is prevented and kill off 40 days herbicidal effects after the dispenser of millet field weed
Embodiment:
