2, the evaluation of synergistic effect
The predictive role of the specific combination of three kinds of reactive compounds can be used so-called " Colby formula " (referring to S.R.
Colby, "Calculating Synergistic and Antagonistic Responses of Herbicide
Combinations ", Weeds 1967,15,20-22) and it calculates as follows: if
A is the activity when the use of dosage being mg/ha or reactive compound A that concentration is mppm；It is expressed as accounting for and not locate
Manage the percentage of control；
B is the activity when the use of dosage being ng/ha or reactive compound B that concentration is nppm, is expressed as accounting for and not locate
Manage the percentage of control；
C is the activity when the use of dosage being hg/ha or reactive compound C that concentration is hppm, is expressed as accounting for and not locate
Manage the percentage of control；
E0It is when using dosage is m, n, h g/ha or concentration are m, when reactive compound A, B and the C of n, hppm
Expection activity,
E0=A×B×C/ (100×(N-1))
N is 3；
If the active E of actual observation is greater than expection activity (E0), then the composition has synergistic effect.
If the actual control of weeds rate observed in biologic test is more than to be calculated using Colby ' s method
Desired value (E), then it represents that the effect of Herbicidal combinations is greater than the summation of each agent effectiveness, it means that composition is made with synergy
