Problems solved by technology

However, at present, the anti-sprouting agent formula with a single active ingredient has an unsatisfactory anti-sprouting effect. The dosage is relatively large, and the residual level in the tobacco leaves during the harvest period is high, which seriously affects the quality of the tobacco leaves and reduces the safety of the tobacco leaves. Some countries implement Stricter limit standards for germination inhibitor pesticide residues have caused serious economic losses to tobacco leaf production in my country

Embodiment 1

[0018] Embodiment 1 anti-sprout active ingredient ratio drug effect test:

[0019] The tobacco variety tested was Yunyan 87. The normal tobacco plants after topping were used as the test materials, and the most commonly used 36% Zhongbuling aqueous emulsion (recommended to be diluted 100 times for application) and 12.5% ​​flumetriamine aqueous emulsion (recommended to be diluted for 300 times for application) were used as test materials. For contrast, with reference to its active ingredient content, according to the conventional method, flumethamine and butyl-line are made into water emulsions of different proportions and carry out drug efficacy test. The drug effect test is totally established as follows (see Table 1), and each process is performed 3 times Repeated, using random block arrangement, 40 plants per treatment. Application method: cup pouring, the amount of drug solution for each plant is 20mL.

Embodiment 2

[0029] According to the conventional method, according to the single-dose recommended dose ratio of 18:6.25, tributamol and secbutaline (i.e. 24.25% tributazone·secbutaline aqueous emulsion, wherein secbutaline 18%, flumetriamine 6.25%), Add different proportions of synergist fatty alcohol polyoxyethylene ether fatty alcohol polyoxyethylene ether Genapol X 060 (1%, 2%, 5%, 8%, 10%) to make water emulsion, dilute 300 times of application, contrast Budding inhibitory effects of different proportions of synergists and without synergists. Other drug efficacy test methods are the same as in Example 1. See Table 3 for test results.

[0032] The above test results show that when 1% to 10% synergist fatty alcohol polyoxyethylene ether Genapol X 060 is added to the formula of s...

Embodiment 3

[0034] In order to compare the residue levels of the new formula mixture of flumetamine and Zhongbutingling with the single agent of sprout inhibitor on the market at the harvest stage, a field experiment was carried out in Longquan Town, Jimo City, Qingdao, Shandong Province.

[0035] On the second day of tobacco topping, the cup spraying method is adopted, and the medicament to be tested is the most commonly used 36% Zhongbuling aqueous emulsion (recommended dosage is 100 times of dilution) and 12.5% ​​flumetriamine aqueous emulsion (recommended dosage is 100 times) on the market. Diluted 300 times), and respectively with above-mentioned two kinds of active ingredients secbutaline and flumethylene content 18:6.25 (24.25% flumethione Zhongbuling aqueous emulsion, wherein secbutaline 18%, flumethylene 6.25%, And contains 5% synergist fatty alcohol polyoxyethylene ether Genapol X 060.

[0036] Carry out field spraying, two spraying doses of single dose are set up low dose (reco...

Abstract

The invention relates to a bud control agent composition capable of reducing bud control agent pesticide residue in tobacco leaves, and the composition is used as a tobacco bud control agent. Specifically, the ratio of effective components flumetralin to butralin is 2.5:28.8-10:7.2. The composition also contains a synergistic agent, i.e. fatty alcohol-polyoxyethylene ether Genapol X 060, and the ratio of the synergist is 1%-10%, preferably the ratio of flumetralin to butralin is 6.25:18, and the ratio of fatty alcohol-polyoxyethylene ether Genapol X 060 is 5%. The composition provided by the invention has bud control effect obviously superior to various single agents one week after pesticide application, and the harvested tobacco leaves have significantly reduced pesticide residue, therefore, the bud control agent composition provided by the invention is a new bud control agent combination capable of enhancing the bud control effect and lowering the pesticide residue level.

Description

technical field [0001] The invention relates to the field of agricultural plant growth regulators, in particular to a sprout inhibitor composition, which can reduce the pesticide residues of the sprout inhibitor in tobacco leaves. Background technique [0002] In the management of tobacco leaf growth, after the budding of the tobacco plants, a large amount of nutrients in the tobacco leaves flow to the reproductive organs, which will inevitably lead to a decrease in the yield and quality of the tobacco leaves. In order to reduce the consumption of nutrients in the leaves and improve the yield and quality of tobacco leaves, topping must be done in time in the later stage of tobacco plant growth. After topping, the top advantage of the tobacco plant is broken, and the tobacco axillary buds will germinate and grow rapidly. Each axillary bud has the ability to bloom and set fruit. If the buds are not wiped in time, the nutrients in the leaves will also be consumed, affecting the...
