According to survey data, the actual preventive effect of each processing is calculated by formula (1), unit is percentage (%), result of calculation
Retain 2 significant digits.
In formula：
E-actual preventive effect；
C-control weeds aerial part fresh weight；
T-processing weeds aerial part fresh weight.
Colby methods：Theoretical preventive effect (it is expected that preventive effect) E of Mixed Pharmacy0(2) formula is calculated：
In formula：
Actual preventive effect when the consumption of X-herbicide 1 is P；
Actual preventive effect when the consumption of Y-herbicide 2 is Q；
Actual preventive effect when the consumption of Z-herbicide 3 is R；
E0The consumption of-herbicide 1 is that the consumption of P+ herbicides 2 is theoretical preventive effect when the consumption of Q+ herbicides 3 is R, i.e. mixture is removed
The expection preventive effect of careless agent；
E-herbicide 1,2 and 3 presses actual preventive effect during different ratio mixture；
As E ＞ E0When, should if that is, the actual preventive effect of Mixed Pharmacy exceedes the theoretical preventive effect (it is expected that preventive effect) calculated
Combination just has super superposition, that is, acts synergistically.
2nd, result of the test
Result of the test refers to table 1~9, it is seen then that active components A (thiophene ketone sulphur grand and fluorine benzofenap) with selected from active component B
