Experimental example downy mildew of garpe controlling experiment
In certain grape experiment field, get 5 pieces of areas and be 20m
2experiment field, be labeled as contrast 1 group respectively, contrast 2 groups, embodiment 3,4 and 5 groups, time of application be downy mildew of garpe morbidity mid-early stage.
Contrast 1 group and spray Ao Like frost Bel (50ml is watered 30 jin), only spray once;
Contrast 2 groups and spray Ao Like frost Bel (50ml is watered 30 jin), spray three times, sprayed once every 5 days;
Embodiment 3,4 and 5 groups sprays the embodiment of the present invention 3,4 and 5 gained pesticide control (being diluted to same concentrations) respectively, only sprays once.
All the other conditions of each piece of experimental field are identical.
Fertilizing method and regular maintenance management carries out all according to a conventional method, finally more each group after medicine 7 days, 14 days and 21 days time, to the control efficiency of downy mildew, the results are shown in Table 1.
Table 1 respectively organizes medicament to the control efficiency of downy mildew
Note: with contrast 1 group and compare, * P<0.05;
Can be drawn by upper table 1, compared with contrast 1 group, namely with only use compared with Yi Ao Like frost Bel, gained pesticide control of the present invention is used once, after medicine, the preventive effect of 7 days, 14 days and 21 days is significantly increased, and do not reduce significantly, show that medicament drug effect of the present invention is given prominence to, the lasting period is long.
Compared with contrast 2 groups, namely with use compared with three Ao Like frost Bels, gained pesticide control of the present invention, suitable to the control efficiency of downy mildew of garpe.Therefore, pesticide control of the present invention is only used once in downy mildew of garpe morbidity mid-early stage, can reach the effect that Ao Like frost Bel uses three times.So medicament of the present invention can reduce the access times of medicine, economizes in raw materials, and environmental pollution can be reduced.
