Effectively, the bakanae disease of rice that especially causes to the microbial head blight of reaping hook, fusarium moniliforme, fusarium oxysporum draw for the disease that causes
The tomato wilt for rising has good prevention effect.2-cyano-3-amino-3-phenylancryic acetate is absorbed by root, has translocatable upwards, face on blade
To blade bottom and interlobate translocatable poor.
Metalaxyl-M (Metalaxyl-M), molecular formula:C15H21NO4.Chemical name:N- (2,6- xylyls)-N-
(Methoxyacetyl)-D- alanine methyl ester.Structural formula:
Metalaxyl-M is the efficient systemic fungicide of Syngenta Co., Ltd's exploitation, with protection and therapeutical effect, can be by plant roots
Stem and leaf absorbs rapidly, and each position is run in plant body, thus resistance of rainwater washing against, to Pseudoperonospora cubensis, phytophthora pathogenic bacteria,
The crop pests such as the vegetable caused by rotten mildew fungus, fruit tree, Nicotiana tabacum L., oil plant, Cotton Gossypii, grain have efficient.
The difficulty of prevention and cure of phytopathogen is increasing at present, on the one hand, with Jing such as the change of pattern of farming, melon fruits and vegetables
Ji crops planting area progressively expands, and disease occurrence degree, generation quantity increase, and in preventing and treating, difficulty is increased;It is another
Aspect, the resistance of pathogen rise under lasting medicament selection pressure year by year, and the prevention effect of single dose is had a greatly reduced quality, phytopathy
Evil preventing and treating is faced with significant challenge.
The content of the invention

Indoor biometricses are tested:
Mycelial growth rate method is adopted indoors, determines different agents to wheat scab bacteria strain (FusaHum
Graminearum Sehw.) EC50Value, using co-toxicity coefficient computational methods, calculates the co-toxicity coefficient (CTC) of mixture,
Determine the building performance of mixture, circular is as follows:
With in mixture, a certain single dose (generally selects EC as standard agent50Junior), calculated:
Single dose toxicity index=standard agent EC50/ certain single dose EC50×100
Toxicity index × the B of the toxicity index of theoretical toxicity index=A single doses × A single doses proportion+B single doses in mixture is mono-
Agent 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/theoretical toxicity index × 100
Co-toxicity coefficient is classified:When CTC is more than 120, mixture has synergetic, and CTC exists for antagonism, CTC when being less than 80
It is summation action between 80-120.
