Description
Technical field
The invention belongs to the disinfectant use in agriculture field.
Background technology
Glyoxalin (imibenconazole), 4-benzyl chloride base N-(2,4 dichloro benzene base)-2 (1H-1,2,4-triazol-1-yl) thioacetamide ester, broad spectrum activity triazole bactericidal agent.Mainly be the biosynthesis that destroys and stop the cell membrane important component part ergosterol of germ, thereby destroyed the formation of cell membrane, cause germ death.
Fluoxastrobin (azoxystrobin); (E)-and 2-{2-[6 (2-cyano-benzene oxygen) pyrimidine-4-base oxygen] phenyl }-the 3-methoxy acrylate; belong to the wide spectrum methoxy acrylic bactericide; the mitochondrial respiratory inhibitor; promptly by shifting to the electronics of cromoci at cytochrome B cl; thereby suppress mitochondrial breathing, have protection, root out, infiltration, systemic activity, suppress spore germination and mycelial growth and produce spore always.
The phonetic phenol of second (ethirimol), 5-butyl-2-ethylamino-4-hydroxyl-6-methylpyrimidine, belong to the miazines bactericide, adenosine deaminase inhibitors, after pathogen contacts, mycelium, conidium, trichogyne there is very strong killing effect, the powerful formation that suppresses spore, systemic fungicide has protection and therapeutic action; Can be absorbed rapidly by plant roots, stem, leaf, and in plant corpus, run to each position, be mainly used in the powdery mildew of control crop.
Propineb (propineb), acrylic bisdithiocarbamic zinc belongs to dithiocarbamates, acts on the synthetic of fungal cell wall and protein, can suppress infecting and sprouting of spore, can suppress mycelial growth simultaneously, causes its distortion, death.And this medicine contains and is easy to the zinc element that absorbed by crop, the quality that helps promoting plant growth and improve fruit.
Tpn (chlorothalonil), daconil M (2,4; 5,6-tetrachloro-1,3-benzene dicarbonitrile); belong to organochlorine class protective fungicide, can with the combined with protein of cysteine in the glyceraldehyde 3-phosphate dehydro-genase among the fungal cell, destroy the metabolism of cell and loss of life power.It mainly acts on is the prevention fungal infection, inhales conduction in not having, but at plant surface good adhesivity is arranged, and is not subject to rain drop erosion, and the long drug effect phase is arranged.
Polyoxin (polyoxin), the broad-spectrum antibiotics class has the interior preferably conduction of inhaling, and its mechanism of action is to disturb the chitinous biosynthesis of bacterial cell wall, germ tube is with after mycelium contacts medicament, expand the part, breaks, and overflows cell inclusion, and can not normal development cause death, suppress germ in addition and produce spore and scab expansion effect, this medicine does not have toxicity to animal, and plant is not had poisoning.Be used to prevent and treat multiple fungal diseases such as paddy rice, wheat, vegetables fruit tree.
In give birth to rhzomorph (zhongshengmycin), belong to N-glucosides class alkaline water soluble substance, the protective fungicide that fungicidal spectrum is wider, have tag, osmosis.Its effect: to bacterium is suppress bacterium protein synthetic, causes thalline death; To fungi is to make the mold fungi deformation of filament, suppresses directly killing spores of spore germination and energy.Bacterial disease and part fungal disease to crops have very high activity, have certain production-increasing function simultaneously.
