It is control to put a filter paper and volatile oil is not added dropwise.It is repeated 3 times.Ware bottom ware lid make-up, sealed membrane sealing, 25 DEG C are inverted culture, 3d
After measure colony diameter, right-angled intersection takes the average value of 2 data, calculates bacteriostasis rate.
Bacteriostasis rate=(control colony growth diameter-processing colony growth diameter)/control colony growth diameter × 100%
The bacteriostasis of 1 metasequoia Volatile Oil from Seed of table
The toxicity test result of 2 metasequoia Volatile Oil from Seed of table
Test result shows that metasequoia Volatile Oil from Seed has garlic leaf blight bacterium and wheat scab and inhibits to make well
With.
(2) field control effectiveness test
In order to preferably verify the practical application effect of the present invention, illustrate that the field efficacy of the present invention tries with example below
Test effect.
The application of fungicide of the present invention is to prevent crop disease as the main purpose, according to different diseases type and plant size
Determine that the administration dosage of unit area, generally per hectare apply 100-150g.
Reagent agent：Microcapsule product, 40% pyrimethanil prepared by the present invention
Subjects：Garlic leaf blight bacterium, wheat scab
Experiment grouping：20 cells are randomly choosed in field, are individual protecting field per cell per plot area 50m2,
20 cells are randomly divided into 4 groups, every group of 5 repetitions, every group of fungicide 100g/hm2 prepared respectively using the present invention is used
A indicates that 120g/hm2 is indicated with B, and 40% pyrimethanil sprays 150g/hm2, is indicated with C, and clear water control is indicated with D,
Dispenser when field starts morbidity, sprays once every 7d, applies altogether 3 times, and spray value is according to each group of design concentration with the leaf that sprays
Until piece liquid drips.
Investigation method：7d and 14d are investigated after last time dispenser.Per cell using 5 points of samplings, every investigation 5
Strain, record morbidity severity, and calculate each cell disease index.Control effect is calculated according to following formula：
Control effect (%)=(check plot disease refer to-treatment region disease refer to)/check plot disease refers to × 100.
Preventive effect of the 3 metasequoia seed hair oil microcapsule formulations of table to garlic leaf blight bacterium and kind wheat scab
As it can be seen that 2 of bactericide of the present invention handle A and B, to garlic leaf blight bacterium, wheat scab from table
Preventive effect be above common chemical bactericide C.And 2 processing of fungicide of the present invention are to garlic leaf blight bacterium, gibberella saubinetii
The preventive effect of disease extends and increases at any time；And the extension of the preventive effect of common chemical bactericide processing C at any time reduces.Thus may be used
See that fungicide release of the present invention is slow, the lasting period is long, can reduce the dispenser frequency of pesticide, cost-effective.
