The preventing and treating of the diseases such as fruit tree, vegetable, field crop；Owing to its distinctive mechanism of action is not likely to produce cross resistance,
In addition to crop safety and favourable toxicity data and ecological effect, it is the Novel tobacco amide-type sterilization of significant
Agent.
Metalaxyl (Metalaxyl), chemical name: D, L-N-(2,6-3,5-dimethylphenyl)-N-(z'-methoxy benzene
Acetyl) methyl lactamine.Structural formula:
Metalaxyl is a kind of systemic fungicide, has protection and therapeutical effect, can be by the rhizome of plant
Leaf absorbs, and along with Water Transportation in object, and transfer to each organ of plant, there is Bidirectional Conduction,
To Pseudoperonospora cubensis, phytophthora pathogenic bacteria and maize ear rot microbial various crop downy mildew, the epidemic disease of melon vegetables class
Mildew, the downy mildew of millet are effective.
At present the difficulty of prevention and cure of phytopathogen is increasing, on the one hand, along with the change of pattern of farming, melon and fruit,
The industrial crops cultivated areas such as vegetable progressively expand, and disease occurrence degree, generation quantity all increase, anti-
Control difficulty to strengthen；On the other hand, the resistance of pathogen rises under lasting medicament selection pressure year by year, single
The prevention effect of agent is had a greatly reduced quality, and control of plant disease is faced with significant challenge.
Summary of the invention
It is an object of the invention to provide a kind of applied widely, low cost, effective for above-mentioned technical problem
Plant bactericidal composition containing Boscalid Yu metalaxyl.
It is a still further object of the present invention to provide this bactericidal composition to cause on fungal disease at preventing and treating plant epiphyte

Embodiment 17:
Indoor biometrics is tested:
In indoor employing mycelial growth rate method, measure the different agents EC to bacterial strain50Value, uses poison system altogether
Number calculating method, calculates the co-toxicity coefficient (CTC) of mixture, determines the building performance of mixture, the specifically side of calculating
Method is as follows:
In mixture, a certain single dose (is generally selected EC as standard agent50Junior), calculate:
Single dose toxicity index=standard agent EC50/ certain single dose EC50×100
Toxicity index × A single dose poison of proportion+B single dose in mixture of theoretical toxicity index=A single dose
Power index × B single dose proportion in mixture
The EC of actual measurement toxicity index=standard single dose50The EC of value/mixture50Value × 100
Co-toxicity coefficient=actual measurement toxicity index/theory toxicity index × 100
When co-toxicity coefficient classification: CTC is more than 120, mixture has synergetic, is short of money when CTC is less than 80
Anti-, CTC is summation action between 80-120.
