Biological activity determination
The indoor Herbicidal of example 7
The former medicinal a small amount of acetone solution of testing compound, then be diluted to required concentration with the water containing 0.1% tween 80.Quantitative weed seed is sowed at respectively diameter be 7cm be equipped with in the dixie cup of Nutrition Soil, broadcast rear earthing 1cm, in hot-house culture after suppression, trickle, thinning after emerging, field planting (gramineous weeds 10-20 strain/cup, broadleaf weeds 2-4 strain/cup), treat the gramineous weeds 2-3 leaf phase, broadleaf weeds grows to 2-4 leaf period, carries out cauline leaf spraying process (spray pressure 1.95kg/cm by test design dosage track type crops sprayer (Britain EngineerResearch Ltd. designs production) 2, spouting liquid 50ml/m 2, crawler track speeds 1.48km/h).3 repetitions are established in test.After liquid natural air drying, be placed in greenhouse and manage according to a conventional method, the situation of growing of routine observation examination material, and according to practical situation, periodical visual inspection investigation reagent agent is to the preventive effect of weeds after process.Preventive effect grade scale: 0 is invalid, 100% for killing weeds completely or seriously suppressing.
The activity data of part of compounds to lady's-grass is as follows:
When drug concentration is 40g a.i./ha, the activity of Compound I a-1 is 100, and the activity of compounds ib-1 is 80%.
When drug concentration is 20g a.i./ha, the activity of Compound I a-1 is 100, and the activity of compounds ib-1 is 80%.
When drug concentration is 10g a.i./ha, the activity of Compound I a-1 is 90, and the activity of compounds ib-1 is 75%.
Compound I a-1 with contrast medicament sulphur humulone (15% aqua, Shenyang Sciencreat Chemicals Co., Ltd. produce) and carry out Herbicidal simultaneously, to the activity data of youth-and-old-age, piemarker, Herba Setariae Viridis and barnyard grass in table 6.
