Description
Technical Field
The invention relates to the technical field of pesticides, and particularly relates to an injection composition for preventing and treating red pine cone pests and application thereof.
Background
The Korean pine is the dominant tree species of natural forests in northeast China forest areas, not only is a precious tree species used, but also is one of the main afforestation and greening tree species. Meanwhile, the Korean pine seeds are rich in grease and protein, are deeply loved by domestic and foreign consumers due to extremely high nutritional and health-care values, are important economic resources in northeast forest zones, are one of important ways for people in the forest zones to become rich, and are one of important driving forces for rapid development of forestry industry. However, in recent years, with the increase of the area of the artificial Korean pine forest and the aggravation of the interference of artificial activities such as picking cones, the original ecological balance is broken, so that the pest and disease damage of the Korean pine frequently occurs, particularly the Korean pine cones and the branch-tip pests are rampant, and huge loss is caused. Most of the species of the red pine cones and branch tips are damaged by transferring between the cones and the branch tips in different stages of life history, so that the branch tips die, the tree crowns are deformed, and the fruits are shrunken. The red pine cone seed flies, the red pine cone seed vespads, the pine cone tip spotted borers, the fir tip spotted borers and the cone planthoppers are main pests of the red pine cones.
In recent years, with the increase of the area of the Korean pine artificial forest in northeast China and the aggravation of artificial interference activities such as picking cones, the harm of Korean pine cones and branch tip pests is increasingly serious, the damage rate of Korean pine cones can reach about 40%, the seed loss rate can reach more than 25%, and the method poses serious threat to forest ecological environment and forestry economic development. The harm of the pine nut not only greatly reduces the yield and the quality of the pine nut and causes huge economic loss, but also seriously threatens the natural renewal of the pine nut and influences the exertion of the ecological benefit of the forest. Because the life of the pests in the larval stage is hidden, the damaged cones or branch tips generate protective fat bleeding reaction, and the liquid medicine is difficult to contact with the pests to play a contact killing effect in the conventional medicament prevention and control process.
At present, chemical control, biological control and forest control measures are mainly adopted for controlling the red pine cone pests. The chemical control adopts tebufenozide, fipronil, abamectin, imidacloprid and beta-cypermethrin for spraying, the control effect is poor, the trunk pesticide injection technology of imidacloprid and thiacloprid is used for controlling Korean pine, a strong pesticide injection method is used for controlling Korean pine, the biological control adopts the functions of spraying bacillus thuringiensis for controlling and releasing parasitic natural enemies, or oligosaccharide is used for assisting in controlling the functions of growth, development, reproduction, insect pest prevention and the like of plants, and the method for forestation under canopy is adopted for the nutritive forest control. The above methods have poor or single effect, or are time-consuming and labor-consuming. Therefore, the development of a pesticide product and a method which can comprehensively control a plurality of mixed insect pests and have outstanding control effect is needed.

Test example 2 (field efficacy test)
Several Korean pine with diameter at breast height of 20cm were selected, and the soluble solutions prepared in examples 1-14 and comparative examples 1-5 were diluted to 100ml each of a solution with 1 wt% active ingredient for use. 50 pinus koraiensis ball flies, pinus koraiensis ball vespids, pinus ostrinia, cottontail pyralid guenee, fir tip pyralid and carpopodium plutella are selected and approximately consistent in size and are respectively dispersedly placed on insect-free trees with good growth states selected in advance, then liquid medicine is injected into the trees in a punching and liquid injection mode, and the death number of target pests is recorded in 48 hours. Each drug solution was subjected to 3 of the above tests and a blank test set (i.e. pest culture only, not administration to trees) was performed. The control effect of each treatment was calculated according to formula (I), and the results are shown in Table 6.
TABLE 6
Note: the blank provides the basis data for the other compositions.
As known to those skilled in the art, when CTC is more than or equal to 120, the CTC shows a synergistic effect, and as can be seen from tables 1 to 5, the weight ratio of the chlorfenapyr to the dinotefuran dextroisomer is 1: (0.01-99), all can realize synergistic action; the weight ratio of the chlorfenapyr to the dinotefuran dextro enantiomer after compounding is 1: (0.1-10) the synergistic effect is obvious; the weight ratio of the chlorfenapyr to the dinotefuran dextro enantiomer after compounding is 1: the synergistic effect is more obvious in (1-5). Wherein, especially when the weight ratio of the chlorfenapyr to the dextrorotatory enantiomer of the dinotefuran is 1: at 1.5, the synergistic effect is best.
Comparing the data of the examples 1 to 14 with the data of the comparative examples 1 to 5, it can be seen that compared with the single use of the chlorfenapyr and the dinotefuran dextroenantiomer and the compound use of the chlorfenapyr and the dinotefuran dextroenantiomer, the injection liquid composition provided by the invention can achieve excellent control effect on various red pine pests; comparing the data of examples 1 to 8 with those of examples 9 to 14, it can be seen that the preferred content of the dextro enantiomer of dinotefuran is 0.1 to 10 parts by weight relative to 1 part by weight of chlorfenapyr, so that more excellent control effect can be obtained; comparing the data of examples 1 to 6 with the data of examples 7 to 14, it can be seen that, in the invention, the preferred content of the dexamectin of dinotefuran is 1 to 5 parts by weight relative to 1 part by weight of chlorfenapyr, especially 1.5 parts by weight relative to 1 part by weight of chlorfenapyr, so that more excellent control effect can be obtained, further crop health can be effectively improved, the dosage can be reduced, the cost can be saved, the residue can be reduced, and the pollution to the environment can be reduced; comparing the data of examples 1-3 with those of example 4, it can be seen that the content of the pesticidal active ingredient in the pesticidal formulation is 0.1-10 wt%, the content of the conductivity enhancer is 0.01-8 wt%, the content of the surfactant is 1-20 wt%, the content of the slow-release agent is 1-20 wt%, and the solvent is complementary to 100 wt%, based on the total amount of the composition. Does not affect the using effect of the injection liquid composition.
The embodiments of the present invention have been described in detail, but the description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention. Any modification, equivalent replacement, and improvement made within the scope of the application of the present invention should be included in the protection scope of the present invention.
