Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of bactericidal composition that contains fluorine bacterium azoles and tpn and be used to prevent and treat powdery mildew, scab, spot defoliation.
Technical background
Fluorine bacterium azoles (triflumizole), structural formula are (E)-4-chloro-α, α, α-three fluoro-N-(1-imidazoles-1-base-α-third oxygen ethylidene) neighbour-toluidines tpn, molecular formula: C

Tpn is a kind of non-internal-absorting wide-spectrum bactericide, and the various crop fungal disease is had prevention effect.Can have an effect with the glyceraldehyde 3-phosphate dehydro-genase among the fungal cell, with the combined with protein that contains cysteine in this enzyme body, the vigor of destructive enzyme is damaged and loss of life power fungal cell's metabolism.The main effect of tpn is to prevent that plant from receiving the infringement of fungi.Received the germ infringement plant, after germ got in the plant corpus, bactericidal action was little.Inhale conduction in tpn does not have, can not be absorbed from the root system of spray medicine position and plant.Tpn has good adhesivity in plant dignity, is difficult for receiving that rainwater etc. washes away, and therefore has the long drug effect phase, can be used to prevent and treat various fungal diseases.
A kind of agricultural chemicals uses on a kind of disease repeatedly, and through after the regular hour, drug effect just obviously goes down, even nearly unavailable, and this phenomenon is exactly that germ has produced pesticide resistance.Drug-fast generation forces the peasant to have to increase dosage and medication number of times, has formed a kind of pernicious upgrading phenomenon so again just.After germ receives the doses action of agricultural chemicals, the death that has, wherein insensitive individuality is just survived; And raise up seed, such offspring's pesticide resistance is just stronger, for preventing and treating the disease that develops immunity to drugs on the agricultural; A kind of method is to release the new component that new and existing kind do not have cross resistance; But the new component development cost is high, and the construction cycle is long, and the speed that develops immunity to drugs less than disease forever; Additive method such as crop allocation adjustment etc. are difficult to play obvious effects in actual mechanical process.Adopting the agriculture chemical compounding of two kinds of different sterilization mechanisms is good prescriptions, owing to obviously improved preventive effect, and reduced dosage, and different classes of active ingredient application point is also different, thereby has delayed the generation of disease drug resistance greatly.
According to repeatedly the test of pesticide effectiveness, prescription screening report and draw that fluorine bacterium azoles and chlorothalonil compound have good synergistic effects, have obviously improved control efficiency, are the important means of integrated control powdery mildew, scab, spot defoliation.
Do not see the report of the bactericidal composition of relevant fluorine bacterium azoles and chlorothalonil compound up to now as yet.
Summary of the invention
The object of the invention proposes a kind of have synergistic effect, use cost is low, preventive effect is good fluorine-containing bacterium azoles and the bactericidal composition of tpn.
The present invention realizes through following technical scheme:
The bactericidal composition of a kind of fluorine-containing bacterium azoles and tpn, wherein fluorine bacterium azoles and tpn percentage by weight are 1～20: 80～1.
