The effect of preventing and weeding the lawn grass and weeds in the farmland and courtyard is more than 95 percent.

Description

The novelty teabag that 1-OCOL is applied as weed killer herbicide
Technical field
The invention belongs to technical field of pesticide, the novelty teabag that 1-OCOL is applied as weed killer herbicide is provided, can the Weeds in Turf grass of efficient, nontoxic, noresidue, farmland weed, garden weeds.
Background technology
In many countries such as China, the U.S., green, the safety of crops receive increasing concern.And weed killer herbicide is as the efficient servicing unit of one, the cultivation management and output lifting of crops play very important effect.But existing weed killer herbicide, mostly tanginess, inconvenience is applied to human settlement, and easily remains, and can work the mischief to people and animals.
1-OCOL, English name 1-Octen-3-ol; 3-Octenol.Have another name called mushroom alcohol (Mushroomalcohol), vinyl amyl carbinol (Vinylpentylcarbinol) or 1-vinyl hexanol (1-Vinylhexanol).Molecular formula is C 8h 16o, structural formula is CH 2=CHCH (OH) CH 2cH 2cH 2cH 2cH 3.1-OCOL is aliphatic unsaturated alcohol, and outward appearance is colourless to pale yellow oily liquid body, has mushroom, lavender, rose and hay fragrance.Occurring in nature, is mainly present in pennyroyal, thyme and fresh mushroom, belongs to natural equivalent spices.In the numerous food product such as the fruits such as banana and berry, beer, pork, river prawn, soybean, also trace contains.Be slightly soluble in water, dissolve in the organic solvents such as ethanol.Industrially produce 1-OCOL by synthesis, instead of be separated from natural goods and produce.
Main application is modulation fragrance and pharmaceutical raw material: (1), for daily use chemicals and flavoring essence, GB2760-1996 is defined as the flavorant allowing to use.Can be used for the preparation type such as mushroom and Earthy Taste essence, artificial essential oil, the essential oil or make ester perfume of recombinating.(2) as chemosynthesis raw material, pharmaceutical field is applied to; As mosquito attractant, be applied to and kill mosquito goods.There is not yet the report that it has herbicidal efficacy.

Embodiment
Below by way of Herbicidal Testing Trials, effective effect of the present invention is described.
(1) 1-OCOL germination rate test
One, 1-OCOL concentration is set to 0; 2.5ml/L; 5ml/L; 10ml/L; 20ml/L5 concentration gradient, each gradient arranges 4-5 repetition
Two, grass-seed is selected: Chinese holly, revolution grass, bermudagrass herb, green foxtail
Three, way is used: select the circular culture dish of 90mm to be that test carried out by container, spread two layers of filter paper by bottom culture dish, select equivalent grass-seed (20) to be positioned on filter paper, then add the reagent of each concentration gradient of 5ml, control group adds sterile water.Then culture dish is positioned in 25 DEG C of insulating boxs and cultivates.
Four, result statistics: adding up the quantity that grass-seed germinates every day, is germination foundation to send out roots, until terminate statistics after not having new seed sprouting.The results are shown in Table 1-table 4.
Table 11-octene-3-alcohol is on the impact (percentage: unit %) of Chinese holly germination percent

From result, when 1-OCOL concentration >=2.5ml/L, iron wire grass-seed germination rate is had a strong impact on.When concentration is 10ml/L, compared with control group, 1-OCOL reaches 91.4% to the inhibiting rate that bermudagrass herb grass-seed germinates; Concentration be >=20ml/L time, the germination of bermudagrass herb grass-seed can be suppressed completely.
(2) 1-OCOL Herbicidal Testing Trials
One, 1-OCOL concentration is set to 0; 2.5ml/L; 5ml/L; 10ml/L; 20ml/L5 concentration gradient, each gradient arranges 4-5 repetition
Two, grass seed selection: Chinese holly
Three, use way: 1, each little basin sowing equivalent grass-seed, water certain water gaging every day, after 3-5 days, grass-seed germinates, and to be averaged when growing to 5cm height, the grouping of Stochastic choice flowerpot arranges concentration gradient test; 2, each flowerpot waters each concentration gradient reagent of (spray) 15ml.
Four, result statistics: 1, image statistics: use front Taking Pictures recording weed growth situation, use the growth differences situation of clapping control group and experimental group weeds rear every day; 2, data statistics: statistics uses front average plant height and strain number with using rear every basin.Continuous statistics one week.The results are shown in Table 5-6, Fig. 1-2.
The pouring of table 51-octene-3-alcohol is to Chinese holly preventive effect
Wherein: strain number (unit: strain); Plant height (unit: cm).
The sprinkling irrigation of table 61-octene-3-alcohol is added up Chinese holly preventive effect
Wherein: strain number (unit: strain); Plant height (unit: cm).
As can be seen from Fig. 1-2, after pouring or sprinkling irrigation 5ml/L1-octene-3-alcohol 24h, just there is obvious difference in the growing way of experimental group and control group Chinese holly, experimental group Chinese holly root there will be rotten situation, cause it to occur lodging, growing way is more weak, after using 3 days, experimental group Chinese holly is basic all dead, and control group Chinese holly then growing way is vigorous.
From result, when 1-OCOL concentration >=2.5ml/L, Chinese holly growing way is had a strong impact on.Use the average plant height of its plant and control group significant difference after 2 days, after 5 days, use the Chinese holly major part or all dead of 1-OCOL.
