5.1 evaluating drug
Synergy type：Test result shows (table 1), mixed with the furans sulphur humulone each combined treatment pair of mesotrione 2
Value >=0 inhibiting rate E-E0 of kind weeds, shows certain increase drug effect trend.
The dosage form that the ratio range and content of selection preparation will be processed with due regard to, if being processed into dispersible oil-suspending agent,
The total content of preparation is unsuitable excessively high, and otherwise viscosity is too big, it is difficult to process, be typically chosen relatively small ratio range.If two medicines
Wettable powder, water-dispersible granules or aqueous suspension agent are processed into agent, and ratio range can be broader.
The mixed synergy effect (Gowing methods) to weeds of 1 mesotrione of table, furans sulphur humulone
Drug evaluation：Mesotrione is shown in Table 1 with furans sulphur humulone to barnyard grass, angustifolia arrowhead herb herbicidal effect measurement result.Five fluorine
There is cross resistance to the resistance barnyard grass for picking up from Ningxia in sulphur grass amine, pyrazosulfuron；Penoxsuam is wild to picking up from Liaoning resistance
Arrowhead no interactions resistance, and pyrazosulfuron has cross resistance to it.Mesotrione and furans sulphur humulone are with 60+36,60+54,60+
72,90+36,90+54,90+72,120+36 mixture composition show synergistic effect to barnyard grass, and E-E0 values correspond to respectively
29.7、21.0、17.8、25.1、17.8、15.1、11.6；To angustifolia arrowhead herb, all combinations all show as synergistic effect.Wherein 90
+ 36 mixture is best to barnyard grass, the effect of angustifolia arrowhead herb, and E-E0 values are respectively 25.1 and 30.0.In addition, in the case of high dose,
Since mesotrione single component preventive effect is higher, uses at this time, often show as addition, this is also mesotrione and furans
Sulphur humulone with 60+36,120+72 mixture combine, although the two ratio is identical, E-E0 values difference the reason of.Therefore,
The considerations such as the balance from cost, preventive effect, herbicide controlling spectrum and formula, mesotrione is with furans sulphur humulone in 1-5:1 range and near
It is mixed more suitable.
The mixed synergy effect (Gowing methods) to weeds of 2 benzobicylon of table, furans sulphur humulone
Drug evaluation：From table 2 it can be seen that furans sulphur humulone is slightly above barnyard grass to the preventive effect of angustifolia arrowhead herb.Nicosulfuron pair
There is cross resistance in the resistance barnyard grass for picking up from Ningxia and the resistance angustifolia arrowhead herb for picking up from Liaoning Yingkou.It is comprehensive to 2 in 9 proportionings
The whole preventive effect of kind weeds, benzobicylon+furans sulphur humulone dosage, which is 600+150 and all of above combination preventive effect, can meet
To the preventive effect of two kinds of weeds.To barnyard grass, low dosage combination shows as synergistic effect, and high dose combination shows as addition；It is right
Angustifolia arrowhead herb, all combinations show as addition.As can be seen that the ratio range of the two is wider, when furans sulphur humulone dosage is low
When, the high dosage of benzobicylon makes up, conversely, when benzobicylon dosage is low, the high dosage of furans sulphur humulone makes up.In addition,
In the case of high dose, since benzobicylon single component preventive effect is higher, uses at this time, often show as addition, this
It is that benzobicylon and furans sulphur humulone are combined with 600+150,1200+300 mixture, although the two ratio is identical, E-E0
The reason of being worth difference.Therefore, from the considerations such as the balance of cost, preventive effect, herbicide controlling spectrum and formula, benzobicylon and furans
Sulphur humulone is in 5-10:1 range and mixed more suitable nearby.
