The way to protect tobacco control from soil-inhabiting pests

 

(57) Abstract:

The way to protect tobacco control from soil-inhabiting pests, combined with the planting of seedlings, uses the principle of simultaneous introduction of mixtures of biological drugs and irrigation water in the row zone. Solutions of drugs prepared directly in containers massageposted machine. Before making a mixture of Biopharmaceuticals (macarisin+Bowery 10 l/ha) at the site to determine the number of soil-inhabiting pests install pheromone traps, and if pest numbers above the economic threshold, additionally produce meats trapping grooves around the perimeter of the field. They are food attractants: protein-vitamin concentrate or forage concentrate lysine (1 kg/ha) for disorientation pests. For trapping and sterilization of adult pests or their disorientation install additional pheromone traps. The use of the proposed method of protection from tobacco terrestrial pests can significantly (87%) to reduce the damage of tobacco and to obtain reliable yield increase (about 5 C), to ensure a positive environmental effect, because it is environmentally safe the th culture to protect against multi-row soil-inhabiting insects. table 1.

The invention relates to agriculture, in particular to the protection of plants against pests and can be used on any agricultural culture in the struggle with the complex of soil-inhabiting pests: moths, click beetles, etc.

The known method of applying various chemicals to reduce the severity of soil-inhabiting pests, the most developed example of phytonematodes [Vorob'eva N. N. Making nematicides with irrigation water // Agroprom. made in: experience, problems and development trends. - Cère.2. - 2. - 1991. - S. 33-41] . Advantages of the method of negatively are that the introduction of nematicides provides good penetration into the soil, uniform distribution, conservation activity for an extended period of time. The nematicides applied with irrigation water using various irrigation equipment. This is a private example of a method of chemicals, i.e. application with irrigation water of agrochemicals, including fertilizers, pesticides, and other chemical meliorants This technique is widely distributed in the United States, Israel, the Netherlands, Italy, Canada, Spain, Germany and others In the U.S. the scale of chemicals reach each year more than 9 million hectares, However, the main disadvantage of this method of negatively is used in the OS), who have contact action and are dangerous, detrimental to the useful accompanying biota.

An increased prevalence and increased severity of soil-inhabiting pests in recent times caused by a lack of effective plant protection, prohibition previously widely used soil insecticides, violation of farming crops. One way of solving this problem is the application of biological preparations.

Also known way to protect tobacco control from soil-inhabiting pests one biological product - matrizen (base - fungus Metarhizium anisopliae), reducing the harmfulness of click beetles by planting tobacco [Filipchuk O. D., Lysenko A. E., Fedin E. A. and other Macarisin protection from tobacco of wireworms // Production of environmentally friendly crop production. The region. recommendations. VNIIBT. - Pushchino. - 1995. - Vol.1. - S. 311-313]. The drug brought in populated pest plot at planting tobacco, together with irrigation water, the rate of flow of 10 l/ha Advantages of this method are the product enters the root zone, where it is localized pest, the larvae of click beetles; optimal hydrothermal conditions for bioagent; there is no need the power of the larvae and adult beetles is within 66-73%, what is often not enough when the number of larvae above the economic threshold (ET=0,5 specimens/m2on tobacco); drug macarisin has little effect on other soil pests, for example, potrisaushih scoop.

The aim of the invention is to increase the efficiency of the method of protecting plants and increase its security.

The way to protect tobacco control from soil-inhabiting insects is as follows. Make a solution of a mixture of biological products (macarisin + Bowery 10 l/ha) on land inhabited by pests in an area of the row simultaneously with irrigation water, when planting seedlings of tobacco, and solutions of drugs prigotavlivaemy directly in containers massageposted machine. Before inclusion in the row zone a mixture of solutions of drugs at the site set pheromone traps, as defined by the number of scoop and click beetles, and if the number is above the economic threshold, additionally produced meats trapping grooves around the perimeter of the field and make them misleading food attractants - protein-vitamin concentrate (PVC) or feed concentrate lysine (KKL) at the rate of 1 kg/ha, in addition install pheromone traps for trapping and sterilization of adults in the preliminary stages: installation of pheromone traps to determine the number, make a mixture of Biopharmaceuticals (macarisin + Bowery 10 l/ha) with irrigation water, combined with the planting of tobacco; cutting trapping grooves and making food attractants; extra pheromone traps for trapping, sterilization or disorientation pests. The proposed method is directed not only against beetles, and other soil-inhabiting pests, for example, potrisaushih scoop, because in addition to metrazine tanks massageposted machine made of Bowery at a dose of 10 l/ha (bioagent - fungus Beauveria bassiama). Pheromone traps designed to determine the number of click beetles and scoop, use periods from birth mass summer imago of a specific type. To identify the number of click beetles installed not less than three, and in determining the number of scoop (winter, exclamation) one 1 ha trap type "Estrone", have them at a certain distance between a given range of pheromone. For food disorientation larvae of click beetles of wireworms on the perimeter of the field cut groove depth of 6-8 cm and made there BVK or KKL in the consumption rate of 1 kg/ha On sites with a low number of click beetles used the trapping of male pheromone traps based 15-20 units/ha is or 24-30 thousand dispensers on 1 hectare Proposed method can significantly improve the effectiveness of protective techniques, because it is comprehensive and covers several types of pests in different phases of their development, is environmentally friendly, because it is based on the use of biologically active substances (pheromones, KKL, PVC) and microbiological preparations (macarisin + Bowery). In addition, when the application of biological products recorded positive growth effects on plants. So, during this period, the survival rate of seedlings of tobacco is faster for 5-7 days and in the future, the plants are best grown. This is because the nutrient substrate used for producing fungus bioagents, has on tobacco a positive effect.

In 1995-1997 way to protect tobacco control from soil-inhabiting pests tested under production conditions in AF "Suzdal" (Krasnodar territory, the Hot Key). Developed techniques to significantly reduce the number of damaged by insects (wireworms, shovels) plant biological efficiency 80-87% at the level of the chemical standard. Medicines and do not have a negative impact on growth, development and yield of tobacco. The pin is made by 28% (see the table at the end of the description).

The use of the proposed method of protection from tobacco terrestrial pests can significantly (87%) to reduce the damage of tobacco and to obtain reliable yield increase (about 5 C), provides a positive environmental effect, because it is environmentally safe for humans and beneficial biota, has a growth promoting effect on plants. This method can be applied entirely on any seedling crop (tomatoes, peppers, cabbage, etc. or in part on any row crop (sugar beet, corn, sunflower) for protection against polyphagous soil-inhabiting insects. The economic effect of the application of the proposed method is (in prices of 2000) 880-1220 rubles/ha in the form of additional net income.

The way to protect tobacco control from soil-inhabiting pests by making solutions of biological and chemical agents in the area, inhabited by pests in the row zone, simultaneously with irrigation water, combined with the planting of seedlings, and solutions of drugs prepared directly in containers massageposted machine, characterized in that make a mixture of biologics (macarisin+Bowery 10 l/ha) in areas of the surrounding pests, moreover, if their number is above the economic threshold (ET), additionally produce meats trapping grooves around the perimeter of the field, they bring food attractants: protein-vitamin concentrate (PVC) or feed concentrate lysine (KKL) at the rate of 1 kg/ha for disorientation pests and install additional pheromone traps for trapping and sterilization of adult pests or their disorientation.
