Description
Technical field
The present invention relates to a kind of medicament, specifically a kind of bactericidal composition of isothiazolone-containing, belong to agricultural technology neck
Domain.
Background technology
Isothiazolone (CAS:It is 55965-84-9) main by CMIT (CIT) and 2-
Methyl -4- isothiazolines -3- ketone (MIT) is constituted.Isothiazolone is risen and kills by disconnecting the key of antibacterial and algae protein matter
Raw effect.After isothiazolone is contacted with microorganism, it promptly can be irreversibly suppressed to grow, so as to cause microorganism thin
The death of born of the same parents, therefore to common bacteria, funguses, algae etc. with very strong suppression and killing action.Kill livestock efficiency high, degradability
Good, with not producing, residual, safe operation, compatibility are good, stability is strong, the low feature of use cost.Can be with chlorine and great majority
Anions and canons and nonionic surfactant are miscible.
Phlorhizin (CAS accession number:It is 60-81-1) to extract from Fructus Mali pumilae, Fructus Mali pumilae bark and leaf etc. and obtain, it is apple tree
Internal aldehydes matter.Phlorhizin be by phloretin and glycocide be glucoside bound into glycosides, its catabolite phloroglucin,
Effect of microbial activitiess etc. can effectively be suppressed.
Actual pesticide experience have shown that, repeats and single-minded applies a kind of reactive compound to prevent and treat harmful fungoid very
To cause the fast selective of fungal bacterial strain in the case of many, be that reduction refractory fungal bacterial strain is selectively dangerous, at present generally
Harmful fungoid is prevented and treated using the mixture of different activities compound.By the way that the reactive compound with the different mechanisms of action is entered
Row combination, can delaying drug resistance produce, reduce amount of application, reduce cost accounting.It is found by the applicant that isothiazolone enters with phlorhizin
Row compounding, with obvious potentiation.
The content of the invention
For the problem that above-mentioned prior art is present, it is an object of the invention to provide the sterilization group containing isothiazolone
Compound, it is to be compounded the sterilization component of two kinds of different structures, the different mechanisms of action, is expanding prevention spectrum and raising drug effect
Effective way, it is often more important that avoid or delay generation of the disease to new composition resistance.To realize the purpose of the present invention, invention
People compounds isothiazolone and phlorhizin, for preventing and treating the disease of crop.
To achieve these goals, the technical solution used in the present invention is:One kind includes two kinds of principle active components:Different thiophene
Oxazoline ketone and phlorhizin.
Described isothiazolone is with the ratio of the parts by weight of phlorhizin, 20:1-1:1.
Described isothiazolone accounts for the 1-40% of medicament gross weight with the weight sum of phlorhizin.
Also include pure water, methyl oleate Polyethylene oxide (30) dimerization hydroxy stearic acid fat.
The present invention under specific ratio by isothiazolone and phlorhizin compatibility by having found have collaboration well anti-
It is 14 to control the effect of leaf spot, the particularly ratio in isothiazolone and the parts by weight of phlorhizin:1-13:Between 1, its collaboration
Prevent and treat leaf muld of tomato effect apparent, whole reagent cost is relatively low, and toxicity is less.

Laboratory test:
Subjects:Leaf muld of tomato pathogenic bacteria
According to the incidence of the whole strain blade of test grade scale investigation Fructus Lycopersici esculenti, disease index and prevention effect are calculated.Will
Prevention effect is converted into niqueMin (y), and medicinal liquid does height (μ g/ml) and is converted into logarithm value (x), and with method of least square virulence is calculated
Concentration EC50 in equation and suppression, according to the abundant methods of Sun Yun toxicity index level co-toxicity coefficient (CTC) of medicament is calculated.
Actual measurement toxicity index (ATI)=(standard agent EC50/ reagent agents EC50) * 100
Percentage composition+B medicament toxicity index * the mixtures of A in theoretical toxicity index (TTI)=A medicament toxicity index * mixtures
The percentage composition co-toxicity coefficient (CTC) of middle B=[mixture actual measurement toxicity index (ATI)/mixture theoretical toxicity index (TTI)] *
100CTC≤80, compositionss show as antagonism, 80 < CTC < 120, and compositionss show as summation action, CTC >=120, group
Compound shows as potentiation.
Table 1 is isothiazolone:Phlorhizin and its different ratio are compounded to leaf spot toxicity test interpretation of result.
From the measurement result of table 1, work as isothiazolone:Phlorhizin proportioning is 14:1-13:When between 1, co-toxicity coefficient
150 are both significantly higher than, with obvious potentiation, and other ratios mix, and co-toxicity coefficient is not obvious.
Field efficacy checking test
Test method:At the initial stage of a disease, first time spraying being carried out immediately, second dispenser being carried out after 7 days, each processes 4
Individual cell, each square meter of cell 20.10 days investigation statisticses incidences before medicine and after second medicine, 5 points of each cell is random
Sampling, 5 plants of crops of per investigation, investigates the lesion area in whole strain per blade and accounts for the percentage rate of blade area and be classified, and calculates
Disease index and prevention effect.
Expected preventive effect (%)=X+Y-XY/100 (wherein, X, Y are single dose preventive effect)
Grade scale:
0 grade:Disease-free spot;
1 grade:Leaf spot lesion is less than 5, and length is less than 1cm;
3 grades:Leaf spot lesion 6-10, part scab length is more than 1cm;
5 grades:Leaf spot lesion 11-25, part scab is linked to be piece, and lesion area accounts for the 10-24% of leaf area;
7 grades:Leaf spot lesion more than 26, scab is linked to be piece, and lesion area accounts for the 26-50% of leaf area;
9 grades:Scab is linked to be piece, and lesion area accounts for more than the 50% of leaf area or full leaf is withered.
The field control effectiveness test of embodiment and matched group to leaf spot.
It can be seen that isothiazolone is with phlorhizin, and the proportioning under certain proportion cooperates with that to prevent and treat leaf spot effect apparent, and
Single isothiazolone has certain prevention effect, single phlorhizin prevention and control capability is also effect on driving birds is not good.Isothiazoline
Ketone is 14 with the ratio of the parts by weight of phlorhizin:1-13:Synergy is most notable when 1, and effect is not during other proportions
It is very notable.
