Abstract
The invention discloses a composition of prohexadione calcium and a fungicide. The composition includes 5 to 50 parts by weight of the prohexadione calcium and 5 to 60 parts by weight of the fungicide; the bactericide is a triazole fungicide such as epoxiconazole, tebuconazole, hexaconazole and difenoconazole, or a carboxylic acid amide fungicide such as thifluzamide and fenoxanil, or a benzimidazole fungicide such as carbendazim and thiophanate-methyl, or an imidazole fungicide such as prochloraz and prochloraz-manganese chloride complex. The composition of the prohexadione calcium and the fungicide provided by the invention can achieve the purposes of vigorous growth control, disease resistance and yield increase, has no effect on next-stubble crops, reduces the pesticide costs of farmers, and increases the crop yield, so as to increase the income of farmers, and create enormous economic and social values.
Description
Technical field
The invention belongs to preparation technique of pesticide field, be specifically related to a kind of Prohexadione calcium and microbicide compositions.
Background technology
Prohexadione calcium is a kind of novel plant growth regulator, is the one of plant growth retardent.It,, by disturbing the biosynthetic final step of GA to work, blocks GA
12aldehyde is to GA
8synthetic, GA activation process is obstructed, and can makes the cell classification element level of ABA, zeatin and isopentenyladenosine type increase.Play and suppress to nourish and grow, promote the effect of reproductive growth, reach the object of increasing production and improving quality.Prohexadione calcium passes through leaf surface treatment, can shorten the cane length of many plants, compared with the triazole type delayer of current extensive use, Prohexadione calcium is to crop rotation plant non-residual toxicity, environmentally safe, can also promote plant nutrition to shift simultaneously, control prosperous length, promote lateral bud growth and root of hair, make cauline leaf keep dark green, improve ripening rate, promote fruit maturation.It also has the disease resistance of enhancing plant, cold-resistant ability, can improve the resistance of crop.Thereby be with a wide range of applications.
As everyone knows; plant growth retardent is to suppress the compound that GA biosynthesis causes plant growth to delay; according to the difference of active position and mode; can be divided three classes: compounds (as chlormequat, first piperazine), nitrogen-containing heterocycle compound (as the paclobutrazol of triazole type, triazolone) and acyl group cyclohexanedione (also claiming cyclohexanetriones); Prohexadione calcium belongs to the one of acyl group cyclohexanedione, is the growth retardant that a class is new.At present Prohexadione calcium is mainly used in the crops such as paddy rice, peanut, Chinese sorghum, has the features such as the prosperous obvious effect of increasing production of control, usage amount are little, low toxicity noresidue.And conventional delayer is as the application of the conditioning agents such as paclobutrazol, uniconazole P, chlormequat, alar-85, ethrel, have that drug effect is more and more not obvious, dosage is increasing always, high residue, the various problems such as expensive, therefore research safety, new varieties and application efficiently, be the active demand that current rice cropping is produced.
Paddy rice is Chinese first cereal crops, lodging is a key factor that affects rice yield, lodging can cause photosynthesis and kernel grouting to stop, greatly affect rice quality, make troubles to harvesting threshing simultaneously, occur shattering, fringe bud phenomenon, increase paddy percent of loss, thereby cause production declining, affect rice quality.The disease of paddy rice mainly contains banded sclerotial blight, false smut, rice blast.The generation of various diseases gently affects grain filling, heavy cause the withered lodging of plant, can not ear, the quality of General Influence rice and the output of paddy rice.Therefore provide one both can control rice lodging, can prevent and treat again the generation of disease, Prohexadione calcium and the microbicide compositions degeneration-resistant, disease resistance that improve paddy rice are very important.
Summary of the invention
For achieving the above object, the technical scheme that the present invention takes is, a kind of Prohexadione calcium and microbicide compositions, and the parts by weight of Prohexadione calcium are that the parts by weight of 5-50, bactericide are 5 ~ 60 parts.
