Description

A method for control of Bemisia tabaci using smoke of dried Nicotiana tabacum leaves}

The present invention relates to a method for controlling tobacco powder using tobacco hay smoke, and more particularly, to a method for controlling tobacco powder including treating smoke generated by burning tobacco leaf hay to a target plant.

Bemisia tabaci is a pest that seriously damages the cultivation of plant horticultural crops such as tomatoes, cucumbers and melons (Brown, JK et al., 2002. Adv . Bot . Res . 36, 65100; Jones, DR , 2003. Eur . J. Plant Pathol . 345, 428434; De Barro, PJ et al., 2006. Biol . Invasions 8, 287294). The pest is also a mediator that indirectly damages more than 200 plant viruses (Brown, JK et al., 2002. Adv . Bot . Res . 36, 65100). In recent years, tobacco powder-mediated tomato Yellew leaf curl virus disease (TYLCV) has been spreading worldwide. In Korea, since the disease was first discovered in tomato planting plant in Tongyeong in 2008, it has been rapidly spreading nationwide (Lee, H et al., 2010. Mol . Cell , 30, 467-476). ). Currently, chemical control using insecticides is used to control tobacco powder , which is a mediator, but it is difficult to control due to the development of insecticide resistance (Byrne, FJ et al., 1994. Bull . Entomol . Res . 84, 179184; Nauen, R. et al., 2002. Pest Manag . Sci . 58, 868-875). On the other hand, in recent years, since the use of chemical pesticides has been restricted due to the rapid increase in organic plant cultivation, development of environmentally friendly plant cultivation pest control methods other than insecticides is urgently needed.

As an environmentally friendly alternative, biological control and insecticidal plant extracts using natural enemies are used, but the control effect does not appear as high as expected. Tobacco ( Nicotiana) Tabacum leaves have been used in pest control since ancient times because they contain nicotine, an insecticide (Schmeltz, I., 1971. Nicotine and other tobacco alkaloids.In; Jacobson M, Crosby DG (eds) Naturally occurring insecticides.Marcel Dekker, New York, pp 99-136).

Accordingly, the present inventors have diligently researched to overcome the problems of the prior arts. As a result, the present inventors smoked the tobacco powder hay in the plant cultivation in a large area where the damage of the tobacco powder is severe, thereby controlling the tobacco powder in large quantities. It was confirmed that the present invention can be completed.

Therefore, the main object of the present invention is very compared to the methods of chemical insecticides, biological control, control using plant extracts, etc., which have been used for the control of Bemisia tabaci , which is the main pest of conventional plant horticultural plants. An effective and economical method is to provide a method for controlling tobacco dust using tobacco hay smoke.

Another object of the present invention is to provide an insecticide and a control device for controlling the tobacco powder using the tobacco hay smoke.

According to an aspect of the present invention, the present invention provides a method for controlling tobacco flour, comprising treating the target plant with smoke generated while burning tobacco leaf hay.

The control method used in the present invention is designed based on the fact that nicotine contained in tobacco has an insecticidal effect and is suitable for large-scale control such as plant cultivation because it uses smoke generated by burning tobacco leaves. In addition, Bemisia , a major pest of conventional horticultural crop plantations, Chemical pesticides, biological controls, and plant extract control methods, which have been used for the control of tabaci ), can be used for a limited number of insect species, or new pest control methods due to the disadvantage that the control effect is not constant and the drug duration is low. As the need for the development of the technology emerges, the possibility of controlling pests of plant horticultural crops using tobacco leaf hay smoke is the result.

Therefore, the present invention is tobacco powder ( Bemisia This is a technical feature in that tobacco leaf hay smoke was used for the first time to control tabaci species. In addition, since the present invention does not require a method for extracting or concentrating nicotine having an insecticidal effect, a simple combustion device can be sufficiently achieved without using a separate device. In addition, since the cost required to control the same immunity compared with the conventional methods for controlling the environment-friendly formulations is relatively economical in terms of cost (see Table 2).

In the method for controlling tobacco powder of the present invention, the target plant may be tomatoes, watermelon, melon, cucumber, cabbage, melon, etc., which are currently being cultivated as plant horticultural crops, which are causing a lot of damage due to tobacco powder. Preferably it is a tomato plant.

According to another aspect of the present invention, the present invention is a combustion tank having a vent hole for combustion in the lower surface and a discharge port for emitting smoke on the upper surface, tobacco leaf hay injected into the combustion cylinder, and the tobacco leaf hay is burned To provide a tobacco dust insect pest control and control device including a combustion device located in the ventilation hole of the lower surface of the combustion cylinder.

The tobacco powder insecticide and control device need only be a combustion device capable of burning tobacco leaf hay without a special device, so it does not need to be particularly limited in construction. In addition, it may be provided with a blowing fan for smooth combustion, a power supply for operating the combustion device and the blowing fan.

The combustion cylinder is suitably made of a metal material because it is necessary to burn the tobacco leaf hay put therein, and the combustion device may be located under or outside the combustion cylinder to supply the high temperature heat required for combustion into the combustion cylinder. As an example of the combustion device, a ignition charcoal, a gas burner, a torch, or the like can be used.

When the combustion cylinder is suspended for about 6-18 hours at 1m above the ground in the facility cultivation site (for example, a plastic house) at the start of combustion, a sufficient control effect can be obtained within a radius of 20m. In the embodiment of the present invention, the insecticidal rate of the tobacco powder was found to be 99% or more, and it was confirmed as a very effective control means (see Table 1).

As described above, according to the present invention can smoke in large quantities by smoking the tobacco leaf hay in the plant cultivation as a whole. This control method is an environmentally friendly, inexpensive and quick control technique that is useful to prevent the spread of tomato sulphurous leaf curling disease as well as pests.

Hereinafter, the present invention will be described in more detail with reference to Examples. These examples are only for illustrating the present invention, and the scope of the present invention is not to be construed as being limited by these examples.

Example .

The test method according to the present invention was carried out on farms that need to be urgently controlled because tobacco powder is rampant (imhari, Y farm, if it is in Andong, Gyeongbuk). This farmhouse is one of the eco-friendly crop cultivation complexes that grow watermelons, melons, cucumbers and cabbages. The treatment was carried out at a stage when the tomato harvest was at the end. Prior to conducting the test, the impact and density of tobacco powder was investigated and summarized in Table 1 below.

Tobacco leaf tobacco smoke treatment according to the present invention was carried out as follows (see Fig. 1). First of all, a rectangular canister (30 × 30 × 40 cm) was prepared and the lid was removed. After lighting fired instant ignition charcoal (Jantae charcoal, Daemyeong charcoal, Korea), it was put in a tin can and filled with tin cans. 20 of these smokers were prepared and hung for 12 hours on 1m above the ground at 20m intervals. After 12 hours of smoking, the density of surviving tobacco powder was measured and summarized in Table 1 below.

In Table 1, by measuring the density of the live tobacco powder before and after 12 hours tobacco hay smoking treatment, it was confirmed that the tobacco powder after the smoking treatment exhibits an insecticide rate of 99% or more, which has an excellent control effect.

In addition, the control method according to the present invention and summarized in Table 2 by comparing the costs required in the method using the environmentally friendly pest control agent that has been used conventionally.

In Table 2, the tobacco leaf hay smoking method of the present invention costs about 30,000 won per 800 pyeong, such as cheaply purchased hay and instant ignited charcoal, while using an eco-friendly insecticide costs about 100,000 won, It was confirmed as an economic way to reduce to 20.
