A fungicidal paste for controlling the rot, dry rot, physalospora canker of fruit tree with high cure rate up to 94-99% is prepared from phellodendron bark, cnidium fruit, dittany bark and viola herb through crushing, decocting, dissolving vaseline and lanolin in it at 50-60 deg.C and mixing with paraffin.

Description

Fungicidal ointment

One, fungicidal ointment is to be coated with a kind of new type bactericide of controlling fruit tree putrefaction disease.Data searching shows, the domestic precedent of still not having application Ointment in Treatment fruit tree putrefaction disease at present.

Two, this invention belongs to the new technical field of agriculture fruit tree bactericide aspect.Ointment means with suitable matrix and adds medicine, is mixed and made into a kind of external use semi-solid formulation of easy coating.It has certain viscosity and plate-out ability, is easy to disperse, and is attached to disease portion, plays the topical therapeutic bactericidal action; Also have slowly-releasing active ingredient, increase the medicament lasting effect, effects such as resistance of rainwater washing against, control efficiency is better than general water-soluble agents.

Three, rot is a kind of destructive disease of fruit tree.The tree vigo(u)r that the apple orchard is injured light weakens, and output reduces, and fruit output is with a toll of 10-15% then; The heavy dead arm of being injured is extremely set, and destroys until the full wafer orchard, and economic loss is difficult to calculate.According to stating in fruit tree research institute of the Chinese Academy of Agricultural Sciences Wang Jinyou, Li Meina, Chen Ce " the generation present situation of China's apple valsa canker and chemical control technology " and Wang Jinyou " apple valsa canker " literary composition; technique of surgical treatment; promptly scrape after the morbidity and control; and control position coating, disinfection protection to scraping, be important measures of integrated control rot.But current China effective agent kind is single, and medicament commonly used contains problems such as arsenic toxin more, and the aqueous solvent lasting period is short, and it is dry easily to run off, and infiltration capacity is few, and field control effect is not ideal enough.The witch need improve.So the screening permeability is strong, the lasting period is long, and protectiveness is good, and has the disinfectant that promotes sick scar healing concurrently, is a task of chemical control.

Four, the purpose of this invention is that screening is efficient, long-acting, pollution-free, the biologic product of noresidue.The formulation of seeking to suit can cover for a long time to scrape and control the position, and it is antibacterial to continue infiltration again, to overcome the shortcoming and defect of medicament commonly used.

Five, the scheme of this invention.Select for use Chinese herbal medicine golden cypress, frutus cnidii, the root bark of shaggy-fruited dittany, Chinese violet as bactericidal agent; Be made into ointment with vaseline, lanolin and paraffin wax as ointment bases.Its prescription is by making) the kilogram product, add golden cypress, the root bark of shaggy-fruited dittany, Chinese violet, each 30 gram of frutus cnidii, vaseline 200 grams, lanolin 200 grams, paraffin wax 100 grams, 500 milliliters in water (soup) amount to 1120 grams.

Manufacturing technique method.(1) earlier with the herbal medicine impurity elimination, sieve, weigh, mix, pulverize, reaching fineness is 100 orders; (2) soaked 12 hours, shift out immersion liquid; (3) will remain the dregs of a decoction and add the water infusion 30 minutes, pour immersion liquid into infusion again, be concentrated in the lump till 500 milliliters/kilogram.(4) pour vaseline, lanolin into another container by proportional quantity, put container in water-bath, keep 50～60 ℃ of temperature, be no more than 60 ℃, make its fusing, merge evenly; (5) container is shifted out water-bath, pour 500 milliliters/kilogram of soup constant volumes, paraffin wax (100 gram/kilogram) into, be stirred to cooling.Product quality is pitchy, paste.

Using method.Operation should be new stubble earlier with the rotten portion of bark scraping, and the edge evenly gets final product the ointment brushing for upright stubble again, does not convert water.

Six, the product of this invention is a kind of botanical pesticide.Include multiple alkaloid, coumarin glucoside, flavonoids and volatilization wet goods active ingredient, have antibacterial by force, bactericidal action.Wherein alkaloid mainly contains jamaicin, phellodendrine, dictaminine, skimmianine, fagarine etc., can suppress germs such as apple valsa canker, pear tree rot, peach rot, and dry rot of apple and ring rot of apple bacterium are also had certain inhibitory action.Facts have proved that above-mentioned medicament combination is to the cure rate height of the bright scab that rots.5 orchards through 3 districts in the suburb of Beijing are on probation, and its cure rate reaches 94～99%, and is coated with 50 times of asomate, and cure rate is 76～88%.

Seven, the ointment production technology is compared with general chemicals production technology, has very high practical value.Its raw material is easily purchased, and equipment investment is few, and production technology is simple, and product cost is low, is suitable for very much the working condition of township enterprise, can go into operation rapidly, promotes product.

Its product also has simple to operate, resistance of rainwater washing against except that advantages such as effective, drug effect is long, directly advantage such as brushing can reduce the orchard to prevent and treat input, and large-area applications is on production of fruit trees.
