Description
Technical field
The invention belongs to pesticides application technical field, is related to a kind of composition pesticide, specifically a kind of pyrrole containing tetrazolium
The bactericidal composition of urethane, applied to controlling plant diseases.
Background technology
In agricultural production process, plant disease occurs seriously, to endanger the nutrition organs such as axis, leaf, and fruit, kind
The organ of multiplication such as son, stem tuber position, influences photosynthesis of plant, influences Leaf-feeding insects outward appearance, crop yield is fallen sharply, under quality
Drop is serious.When disease occurs serious, crop is caused to be had no harvest.Therefore, plant disease in produce reality there is important preventing and treating to anticipate
Justice, bactericide are the most economic, the quick and effective methods of controlling plant diseases.
Single bactericide is limited using easily developing immunity to drugs or preventing and treating spectrum, can not solve well in produce reality
Plant disease endangers.Mixture bactericide, which has to expand, prevents and treats spectrum, enhancing preventive effect, delays the advantages such as the phytopathogen resistance to the action of a drug,
Turn into most popular application form in production practices.Especially there is the bactericide of synergy, each effective group of bactericide
Divide interphase interaction, make combination aging fruit better than the theoretical summation that effect is used alone, thus thing can be played in actual use
The effect of half work(times, is more favored by user.
Tetrazolium pyrrole urethane (picarbutrazox) is the new type bactericide developed by overseas enterprise, is mainly used in preventing and treating vegetable
The diseases such as dish downy mildew, late blight, samping off.CAS accession number is 500207-04-5.Its structural formula is as follows：
