Abstract
The invention discloses a weedicide and application thereof. The active component of the weedicide consists of bensulfuron methyl and acetochlor; and the mass ration between the bensulfuron methyl and the acetochlor is 3/1 to 6/1. The invention mixes the bensulfuron methyl with acetochlor according to a certain proportion, and can effectively extinguish convolvulaceae liana and can especially and quickly extinguish overground and underground biological tissues of ipomoea cairica. The weedicide can be quickly degraded in soil and is environment-friendly; and weeds are not apt to generate resistance; and simultaneously the invention can overcome defects that the manual weeding is incomplete and the repeated weeding is always required.
Description
Technical field
The present invention relates to agricultural chemicals and noxious plant control field, specifically, relate to a kind of weed killer herbicide at noxious plant.
Background technology
Ipomoea cairica (Ipomoea cairica) is Convolvulaceae (Convolvulaceae) herbaceous perennial vine, originate in North America, now be distributed widely in the torrid zone and subtropical zone, spread in China's south China Zhu Sheng large tracts of land in recent years, only its area coverage has reached more than 40 ten thousand square metres in the Baiyun Mountain Scenic Spot of Guangzhou, has become one of the most serious Exotic Harmful Plants of Guangzhou and even whole South China harm at present.For many years its artificial removing is not only expended a large amount of manpower and financial resources, and preventive effect is impermanent, the phenomenon of waking up from death often occurs.
Summary of the invention
The objective of the invention is to overcome the deficiency that existing control technology exists, a kind of Ipomoea cairica obvious results weed killer herbicide that is used to prevent and treat is provided.
To achieve these goals, the present invention adopts following technical scheme:
The active component of weed killer herbicide of the present invention is made up of Nongdeshi and Acetochlor, and its mass ratio is 3: 1～6: 1.Can add various conventional auxiliary agents (emulsifier, cosolvent, adhesive agent or dispersant etc.) according to actual needs in active component, the auxiliary agent proportion is no more than 1/5 of gross mass.Above-mentioned mixing formula can be made into the various formulations of pesticide.
Compared with prior art, the present invention has following beneficial effect: the present invention proportionally is mixed Nongdeshi and Acetochlor, can effectively kill Convolvulaceae liana noxious plant, especially can effectively kill the ground and the terrestrial life tissue of the Ipomoea cairica in the group fast.Weed killer herbicide of the present invention is rapid in degraded in soil, and is environmentally safe, and weeds are difficult for producing resistance, have avoided artificial removing not thorough simultaneously, need the trouble of removing repeatedly.
Embodiment
Embodiment 1
3g Nongdeshi and 1g Acetochlor are dissolved in the 30L clear water, add 1g emulsifier arylsulphonate and 1g cosolvent ethyl acetate simultaneously, fully stir, promptly get weed killer herbicide.
Embodiment 2
6g Nongdeshi and 1g Acetochlor are dissolved in the 30L clear water, add 1g emulsifier arylsulphonate simultaneously, fully stir, promptly get weed killer herbicide.
Embodiment 3
4g Nongdeshi and 1g Acetochlor are dissolved in the 30L clear water, add 1g emulsifier arylsulphonate simultaneously, fully stir, promptly get weed killer herbicide.
Embodiment 4
The weed killer herbicide of embodiment 1 is tested the killing effect of Ipomoea cairica:
1. choose: chosen 3 places chemical control experiment sample ground in October, 2008 in forest farm, White Cloud Mountain, Guangzhou, each sample area is 15 * 6m sample
2(rectangle), gross area 270m
2, the cover degree of Ipomoea cairica is not less than 60% in the sample ground.
2. application method and dosage: the weed killer herbicide of embodiment 1 is dissolved in the clear water, is configured to suspension, concrete consumption such as table 1.Select fine in the afternoon, be advisable, utilize sprayer directly to plant stem, the even spray liquid in blade face, till the soup on the Ipomoea cairica blade has just begun trickling with calm or breeze conditions.After the dispenser in 24 hours if meet rain, need carry out dispenser again, after 24 hours, soup is absorbed by plant, so can ignore by the influence of weather.
7 days, 14 days, 21 days, 28 days and 60 days are observed the Ipomoea cairica of dispenser after dispenser, and write down root, the stem of Ipomoea cairica plant under every kind of processing, the growing state and the withered rate of cauline leaf of leaf respectively.
Use the dose form of the weed killer herbicide of embodiment 1 each sample of table 1.
Theoretical dose is meant the dry weight of herbicidal activity composition.
Experimental result: after 60 days, the ground of Ipomoea cairica and terrestrial life body are all dead in all dispenser sample ground.The Herbicidal mixture agent prescription that each dosage is described all has better killing to remove effect to Ipomoea cairica stem, leaf, root, and preventive effect shows certain Gradient Effect, concrete preventive effect (table 2) as shown in the table along with the increase of dosage.
The weed killer herbicide of table 2. embodiment 1 removes effect to killing of Ipomoea cairica
Claims (2)
1. weed killer herbicide is characterized in that active component is made up of Nongdeshi and Acetochlor, and its mass ratio is 6: 1～3: 1.
2. the application of the described weed killer herbicide of claim 1 in the control Ipomoea cairica.
