Problems solved by technology

The forest herbicide Wilbur or 5% hexazinone and 15% glyphosate ammonium salt are used to spray the Admiralty vine, although the control effect is good, but the dose required is large, and the residual time in the soil can be as long as 8-10 days. months, affecting the ecological environment
[0004] At present, there are not many types of pesticides suitable for the control of local harmful vines, which have the disadvantages of large amount of use, large phytotoxicity to other trees and shrubs, and long residual period in the soil.

Embodiment 1

[0042] Proportion raw materials according to the following weight percentages: 20% of amiloride, 3% of 2,4-dichlorophenoxyacetic acid, 1% of bentazone, 1% of sulfuron-methyl, 0.5% of alkylbenzenesulfonate, wood Sulfonate 1%, xanthan gum 2%, ethanol 2%, add water to 100%, mix and stir to make water agent.

[0043] During application, the above-mentioned water agent was sprayed according to the dosage and time in Table 1, and at the same time, Morizazin (a wettable powder with a purity of 75%) was used as a comparative example for comparison.

[0044] Table 1 The change of the cover degree of two kinds of pesticides to control and control the powder leaf beetle

[0045]

[0046] From the data and comparison in Table 1 Figure 1A-1B and Figure 2A-Figure 2B It can be seen that the control effect of Sencaojing alone on the local harmful vines is not good. After 4 months, the cover degree of S. chinensis recovered to more than 75%, and the application of 12000ml·hm -2 The con...

Embodiment 2

[0049] Proportion raw materials according to the following weight percentages: 23% of amiloride, 2% of 2,4-dichlorophenoxyacetic acid, 2% of bentazone, 1% of metsulfuron-methyl, 1% of alkylbenzenesulfonate, poly Vinylpyrrolidone 2%, methylcellulose 2%, glycerol 8%, and then add water to 100% to form a medicament.

[0050] When applying, the above-mentioned medicaments should be mixed according to 10000-20000ml / hm 2 , add 100g of washing powder, and then add 600L-1000L of water, mix and stir to make a suspension, and then spray it on the leaves and stems of the chicken dung vine. After one month, the chicken dung vine in this area has basically withered. Dung vine has a better killing effect.

Embodiment 3

[0052] Proportion raw materials according to the following weight percentages: 25% of amiloride, 2% of 2,4-dichlorophenoxyacetic acid, 1% of bentazone, 0.5% of metsulfuron-methyl, 0.5% of alkylbenzenesulfonate, poly Sodium acrylate 2%, sodium alginate 3%, glycerol 8%, add water to 100% to form a medicament.

[0053] When applying, the above-mentioned suspending agent should be mixed according to 4500ml / hm 2 , add 1L of detergent, then add water 600L-1000L, spray on the leaves and stems of kudzu plants, and after one month, the killing rate of kudzu is 100%, which has a good killing effect.

Abstract

The invention provides a composition for preventing and controlling local harmful vines. The composition is prepared from picloram, 2,4-dichlorphenoxyacetic acid, bentazone and sulfometuron, wherein the mass ratio of the picloram to the 2,4-dichlorphenoxyacetic acid to the bentazone to the sulfometuron is (20-30) to (2-5) to (0.5-2) to (0.5-1), and the mass percent after combination is 24-30% of the total mass of the composition. The composition is further prepared from a cosolvent, the cosolvent is prepared from alkylbenzene sulfonate, a dispersing agent and a thickening agent, the mass ratioof which is 1 to 1 to (2-1) to 1 to 4, the mass percent after combination is 2-6% of the total mass of the composition. According to the composition, various raw materials have complementary advantages and synergistic effects, the effectiveness of killing the local harmful vines is remarkable, the dosage is low during use, the phytotoxicity caused to trees and shrubs is small, the pollution to soil is small, and the ecological safety is high. The invention further provides application of the composition for preventing and controlling the local harmful vines.

Description

technical field [0001] The invention belongs to the technical field of harmful plant control, and in particular relates to a composition for preventing and controlling native harmful vines and an application thereof. Background technique [0002] Lianas are an important structural component of vegetation communities. They are a type of plants whose stems are soft and cannot stand upright freely. They need to rely on the stem itself or other objects to climb, twine or crawl. Most vines are conducive to enriching the structure and function of the forest ecosystem, maintaining the stability and positive evolution of the forest ecosystem, but there are also some vines that multiply, spread, entangle, cover, strangle, and crowd out other plants, seriously destroying the original forest The plant community structure causes forest degradation, functional decline, and biodiversity reduction. Such vines are called harmful vines. Harmful vines can reduce tree growth rate, cause tree ...
