The behavior of the experimental herbicide CGA 152005 in relation with soil moisture was investigated in two experiments performed in laboratory at the Agriculture Graduate Program of the ITESM.
}
The product was applied at 30 i.a./ha; sunflower (Helianthus annuus) was used as indicator of bioactivity. In the first experiment were observed the effects in soil at 65, 75 and 85% field capacity and CGA 152005 was applied in preemergence. In the second experiment CGA 152005 was applied on soil at 70 and 80% field capacity, then samples at 2, 4 and 6 cm were taken and placed in containers and the indicator plant was seeded.
Results show that the herbicide does not affect germination but a severe growth inhibition of both, radicale and hipocotyl was induced in both experiments. There is significant difference between 70 and 80% field capacity; the inhibition is greater at 80%.
