Abstract
The present invention discloses a pesticide composition containing 2,4-D and 1-methylcyclopropene. The pesticide composition comprises an auxiliary agent, 2,4-D and 1-methylcyclopropene. The weight ratio of the 2,4-D and 1-methylcyclopropene is 30 : 1 to 1 : 10. The pesticide composition has obvious synergic functions on freshness preservation of oranges and tangerines.
Description
Technical field
The composition pesticide that the present invention relates to, is with 2, and it is activity that 4-drips with 1-methyl cyclopropene
Composition, has synergism to Citrus are fresh-keeping, it is adaptable to Citrus are fresh-keeping.
Background technology
It is raw that 2,4-drips (2,4-D or 2,4 dichlorophenoxyacetic acid) representative synthesis plant
Long element (auxin), is a kind of auxin analog, can be used for coordinate plant growth and conduct
Selective herbicide uses.
1-methyl cyclopropene (1-Methylcyclopropene), is abbreviated as 1-MCP, is one
Plant very effective ethylene to produce and the inhibitor of ethylene action.As promoting planting of ripening and senscence
Thing hormone ethylene can be produced by Activities of Some Plants self, again can be at storage environment even air
In there is a certain amount, ethylene with thin fertile within associated receptor combine, could activate one is
Arrange the biochemical reactions relevant with maturation, accelerate old and feeble and dead.L-MCP can also be fine
Ground is combined with ethylene receptor, but this combination will not cause ripe biochemical reaction, therefore,
Plant endogenous ethylene produce or exogenous ethylene effect before, use 1-MCP, it will try to be the first with
Ethylene receptor combines, thus stops the combination of ethylene and its receptor, extends fruit and vegerable well
The process of ripe aging, extends freshness date.Can delaying ripening, aging well, protect well
Hold the hardness of product, brittleness, keep color, local flavor, fragrance and nutritional labeling, can be effectively
Keeping the disease resistance of plant, alleviate that microorganism causes rots and alleviates physiological disease, and can subtract
Few moisture evaporates, prevents from wilting.Under room temperature state, 1-methyl cyclopropene is gas, 1-methyl
Cyclopropylene can be deposited with the powder type of alpha-cyclodextrin molecule or beta-schardinger dextrin-molecule Rubber Capsule
, it is also possible to exist with the powder type of other cyclodextrin molecular Rubber Capsules.
The present inventor is found through experiments, and by 2,4-drips with 1-methyl cyclopropene according to certain
Part by weight mixture, has obvious potentiation to Citrus are fresh-keeping.
Summary of the invention
Drip and the potentiation of 1-methyl cyclopropene it is desirable to provide a kind of effective ingredient is 2,4-
Composition pesticide, effectively manages instrument for Citrus fresh-keeping offer one.
Technical solution of the present invention: a kind of drip and the pesticide combination of 1-methyl cyclopropene containing 2,4-
Thing, it is characterised in that: include usual auxiliaries, 2,4-drips and 1-methyl cyclopropene, and 2,4-drip
It is 30:1～1:10 with the ratio of weight and number of 1-methyl cyclopropene.2,4-drips and 1-methyl ring third
Alkene weight summation percentage by weight in composition pesticide is 0.1%～30%
In the present invention, 1-methyl cyclopropene is encapsulated with alpha-cyclodextrin molecule or beta-schardinger dextrin-molecule
The powder type of capsule exists.
Composition pesticide of the present invention can be adopted according to well known to a person skilled in the art method
With suitable auxiliary element, it is processed in the applicable agricultural production such as wettable powder, soluble concentrate
The application forms used.
Described wettable powder formulation weight percent consists of: 2,4-drip 0.1～20%,
1-methyl cyclopropene 0.1～10%, dispersant 0.1～14%, wetting agent 0.1～12%, solid
Carrier complements to 100%.Concrete production stage is: concrete production stage is: by effective ingredient
Mix with other auxiliary agent, again through comminution by gas stream, mix homogeneously after mechanical activation comminution, prepare corresponding weight
The powder of amount percentage composition, 1-methyl cyclopropene divides with alpha-cyclodextrin molecule or beta-schardinger dextrin-
The powder type of attached bag capsule exists.
Described soluble liquid weight percent consists of: 2,4-drip 0.1%～20%, 1-first
Cyclopropene 0.1～10%, solvent 1～40%, dispersant 0.1～14%, emulsifying agent 0.1～
12%, liquid-carrier complements to 100%.Concrete production stage is: effective ingredient and solvent are mixed
Closing, mix with other auxiliary agent after fully dissolving, liquid-carrier complements to 100%, mix homogeneously,
Preparing the soluble liquid of corresponding weight percentage, 1-methyl cyclopropene divides with alpha-cyclodextrin
The powder type of son or beta-schardinger dextrin-molecule Rubber Capsule exists.
Composition pesticide of the present invention is obvious to fresh fruit increment rate synergism fresh-keeping on mandarin tree, relatively
Single dose be used alone and significantly improve the fresh-keeping effect to Citrus；Reduce Pesticide use amount,
Decrease use cost, Environmental compatibility good.
