Description

The application of a kind of 35% Phoxim microcapsule agent aspect control root of herbaceous peony grub

Technical field

The present invention relates generally to a kind of application of 35% Phoxim microcapsule agent, relates in particular to the application of a kind of 35% Phoxim microcapsule agent aspect control root of herbaceous peony grub.

Background technology

The root of herbaceous peony is the dry root of ranunculaceae plant Chinese herbaceous peony Paeonia lactiflora Pall, cold nature, bitter, acid, return Liver Channel, there is the function of flat liver pain relieving, nourishing blood for regulating menstruation, astringing YIN to stop sweating, cure mainly that dizzy, the hypochondriac pain of headache, stomachache, four limbs contraction pain, the deficiency of blood are sallow, irregular menstruation, spontaneous perspiration, night sweat etc.The root of herbaceous peony is one of conventional 40 kinds of bulk medicinal materials of China, and consumption is huge, in traditional Chinese medicinal materials assortment, ranks among the best, and it is reported that a whole nation year sales volume for white Peony Root can reach more than 40000 tons, exports 2000 tons, is China's export one of the maximum kind of earning foreign exchange.Main product in Anhui, Zhejiang, Sichuan, with Bozhou, Anhui Province output maximum, account for the more than 80% of national root of herbaceous peony output.

The root of herbaceous peony belongs to perennial grass origin class medicinal material, and general 3-5 after field planting collects root.Underground pests is the key factor that affects root of herbaceous peony product quality, output and safety, becomes the restraining factors of local root of herbaceous peony producing region development.The main soil insect of the harm root of herbaceous peony is grub (chafer larva).Grub lives in soil, root of herbaceous peony Tanaka, mainly gnaws tender of the children who bites root of herbaceous peony plant, forms root cavity, scar, has a strong impact on the yield and quality of the root of herbaceous peony, when serious, can cause the whole strain of one year seedling withered.Grub is mainly distributed in the above soil layer of 20cm, and with worm amount maximum in 11～20cm soil layer, the following insect amount of 30cm is very little.First-instar young is multiple in 7～October, and July, amount was maximum, and second instar larvae is maximum 8～September, and therefore, be crucial season of control 7～September.

At present, the control of grub mainly depends on chemical pesticide, conventional phoxim granule, phoxim emulsifiable concentrate and thimet etc.Conventional control technology in production: need to prevent and treat every year 2 times, while being once field planting, dispenser or early April in spring are in conjunction with the root dispenser control Overwintering Larvae that dries in the air; The low instar larvae that summer, (early and middle ten days in July) dispenser control was hatched then then for the second time.Due to above-mentioned medicament, holding the medicine phase is 1～February, needs repeatedly dispenser in production, and time-consuming, cost accounting is high; And because medicament is difficult to apply the movable hazard area of grub, and it is not good to cause control efficiency; In phoxim emulsifiable concentrate, more than 50% be benzene class organic solvent simultaneously, contaminated environment; Indivedual peasant households, in order to pursue control efficiency, are used violated high-toxic pesticide, as thimet, also likely cause residue of pesticide to exceed standard, and affect the safety of medicinal material.Therefore, how to accomplish efficient, easy, safe prevention root of herbaceous peony soil insect, be the technical barrier on producing always.

Summary of the invention

The object of the invention is just to provide the application of a kind of 35% Phoxim microcapsule agent aspect control root of herbaceous peony grub.

The present invention is achieved by the following technical solutions:

The application of 35% Phoxim microcapsule agent aspect control root of herbaceous peony grub, 35% described Phoxim microcapsule agent has new purposes aspect control root of herbaceous peony grub.

The application of 35% Phoxim microcapsule agent aspect control root of herbaceous peony grub, 35% described Phoxim microcapsule agent is comprised of the raw material of following weight parts:

Phoxim crude 10-20, carrene 80-90,2,4-toluene di-isocyanate(TDI) 10-12, polyvinyl alcohol 1-2, dodecylbenzene sodium sulfonate 0.1-0.3, ethylenediamine 0.4-0.6, water are appropriate.

Advantage of the present invention is:

(1) prevent and treat efficiency high: root of herbaceous peony growth cycle is long, the grub harm phase is also longer.New product target is held medicine phase 1-2, a dispenser, and 2 years are effectively, saving of work and time, and control efficiency is more than 90%;

(2) low toxicity, low-residual: product main component is necessary for low toxicity, less-persistent pesticide;

(3) benefit that increases production and improves productivity: product yield improves more than 25%, and commodity greatly improves, and primes ratio can reach more than 95%, according to market price estimation in 2013, the more common product price of primes improved 1.5 yuan/kg, and a mu planting benefit can improve 5000 yuan of left and right.

Accompanying drawing explanation

Fig. 1 is yield comparison figure of the present invention.

Embodiment

The present invention uses the phoxim microcapsule controlled-release agent (long-acting, efficient, low toxicity, low-residual) of Institute of Plant Protection, academy of agricultural sciences, Anhui development, and when the root of herbaceous peony is transplanted, medicament is watered to spraying or sand cutting, and to impose in transplanting cave be earthing.

Table 1 and Fig. 1 have listed after dispenser the investigation result of the control efficiency of 2 years.

Table 1: the present invention's 35% Phoxim microcapsule agent is in the comparison of control root of herbaceous peony grub effect

The present invention applies the beneficial effect bringing:

1, long-acting: the lasting period reaches 2 years, compared with missible oil, granule, grow 22 months.

2, efficient: insecticidal effect is greater than 90%, compared with conventional dose, increases more than 30%.

3, easy, saving of labor a: dispenser in sowing time, conventional need 2～3 times.

4, low toxicity, nuisanceless: product main component is phoxim, can decompose under illumination condition 3～6 days completely.

5, synergy: increase production more than 25% than conventional dose control.

Claims (2)

1. the application of 35% Phoxim microcapsule agent aspect control root of herbaceous peony grub, is characterized in that 35% described Phoxim microcapsule agent has new purposes aspect control root of herbaceous peony grub.

2. the application of a kind of 35% Phoxim microcapsule agent according to claim 1 aspect control root of herbaceous peony grub, is characterized in that what 35% described Phoxim microcapsule agent was comprised of the raw material of following weight parts:
