Description
Technical field
The invention belongs to technical field of pesticide, and in particular to a kind of botanical fungicide and its system for preventing and treating cucumber downy mildew
Preparation Method.
Background technology
Cucumber downy mildew is caused by Oomycete mould category fungal attack, is occurred more after yielding positive results, from bottom old leaf
Start to fall ill.There is water stain shape, light green color spot in early stage, vacuum side of blade, and it is in polygonal to be limited after expansion by vein, scab
Color change is green, yellow, eventually becomes brown, the mould layer of atropurpureus is grown on the scab of the moisture conditions lower blade back side.Cucumber
Downy mildew is a kind of destructive disease, is commonly called as " horse race is dry ", " dry leaves ", once morbidity, development is swift and violent, so sending out ahead of time
Existing, preventing and treating is very crucial in time.This disease can all occur in each breeding time, mainly cause harm blade relatively conventional with the middle and late growth stage,
Often elder generation is at canopy room droplet dew or the place that prevents wind from passing through, formation infection center are rapid afterwards to spread.
The appearance and use of chemical pesticide, while crop yield and agricultural productive force is greatly improved, unavoidably
Bring some negative effects on ground, such as the harm to human health, the pollution to environment, the influence to non-target organism, resistance
Development and agriculture stability decrease etc..With the enhancing of people's environmental consciousness, highly desirable to find mechanism of action only
Special and environment amenable new control agent, in this case, plant-source antibacterial material is because good, right with being compatible with the environment property
The selection pressure of harmful organism is small, meets the requirement of social sustainable development, and has attracted the pass of more and more pesticide research persons
Note, turn into bactericide research and development focus in the world.
