Description
Technical Field
The invention belongs to the technical field of pest control, and particularly relates to a plant source mixed pesticide and application thereof.
Background
Tea lesser leafhopper is one of the main pests of tea trees in China. More than 60 leafhoppers exist in China, wherein Empoasca onaukii (the protoname pseudoeye leafhopper) is the dominant species of the leafhopper in tea gardens in China (Xiaoqiang, 2015). The worm has strong reproductive capacity and overlapping generation in field. After the insect absorbs a large amount of juice of tea trees, new leaves of the tea trees are damaged, the growth of the tea trees is retarded, and finally, the yield is reduced and the quality is reduced (Lihongli, etc., 2017). In addition, the lesser leaf hopper also damages some field vegetable crops and grapes (Zhang Jun Dai et al, 2017).
At present, the prevention and treatment measures of the empoasca vitis are mainly as follows: (1) agricultural prevention and control; (2) physical prevention and control; (3) chemical prevention and control; (4) and (4) biological control. Biological control of tea lesser leafhoppers includes protection and utilization of natural enemies of tea garden pests such as spiders (Chenyinfang et al, 2004), control using plant-derived and microbial-derived pesticides, and the like (Xieishengyu et al, 2017). At present, the control of tea lesser leafhoppers is still mainly based on chemical pesticides (Shao et al, 2016; Lihongli et al, 2017). The resistance of tea lesser leafhoppers is significantly enhanced over the past, mainly due to the unregulated, unscientific and large-scale single use of chemical pesticides over the years (Caiet al, 2016). Tea leafhoppers have developed a high resistance to long-term use of chemical pesticides such as imidacloprid, acetamiprid, bifenthrin, and the like.
The botanical pesticide is prepared by extracting components with biological activity from plants, and has the following advantages compared with chemical pesticides: (1) the biological activity is various; (2) the pests are not easy to generate resistance; (3) the safety to human and livestock is high; (4) is safe to natural enemies of pests; (5) compared with chemical pesticide, the preparation method is simple. Therefore, the pesticide avoids the problems of environmental pollution and food safety, can be well used as a substitute of chemical pesticides for pest control, and is an ideal pesticide for green control in agricultural production (Pavela et al, 2016).
At present, there are 5 kinds of botanical insecticides registered for controlling tea lesser leafhopper: rotenone, azadirachtin, matrine, pyrethrin and tea saponin are single agents, and no product registration of plant source mixed pesticides exists. The 30% tea saponin aqueous solution is a product registered by the subject group member unit of the applicant of the invention. Since 2007, the applicant of the present invention has developed a study of controlling pests in tea gardens with 30% aqueous tea saponin solution in domestic. In 2015, a 30% tea saponin aqueous solution is approved for temporary registration of pesticides. In 2018, 30% tea saponin water was approved by Ministry of agriculture for pesticide registration. The botanical insecticides such as tea saponin aqua and the like have the common characteristics of lower control effect on pests than chemical insecticides, slow response, and the defects or shortcomings of European Union limit standard, easy decomposition of visible light, higher requirement on application conditions and the like. At present, the field control effect of the 30 percent tea saponin aqueous solution on the tea lesser leafhoppers is only about 60 percent (the field control effect is more than 70 percent, which is ideal), and the field control requirement of the tea lesser leafhoppers cannot be met.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to examples, and the equipment and reagents used in the examples and test examples are commercially available without specific reference. The specific embodiments described herein are merely illustrative of the invention and are not intended to be limiting.
The invention discloses a plant source mixed pesticide and application thereof, and concretely relates to the following embodiments.
Example 1 prevention of tea green leafhopper by tea saponin and azadirachtin in different proportions and diluted combinations
The test of the embodiment is carried out in a tea yard of bealock at Shibata city, Shibata, Hubei, and the target of prevention and treatment is tea lesser leafhopper. The tested insecticide was a 30% tea saponin aqueous solution and 0.3% azadirachtin emulsifiable concentrate according to 3: 1. 2: 1. 1: 1. 1: 2 and 1: 3, mixing in 5 proportions, and diluting each proportion by 4 times: 300 x, 450 x, 600 x and 750 x. The total of 5 × 4 is 20 treatment combinations, and the treatment combinations are respectively numbered TAM1 and TAM2-TAM 20. Control insecticides and concentrations were formulated as shown in table 1.
The cell arrangement and pesticide application method comprises the following steps: cell random block arrangement with cell area of 20m2Repeat 3 times. The pesticide is applied in the high-incidence period of tea lesser leafhoppers. A knapsack sprayer-duster (model: 3WF-3A) is used for uniformly spraying water on the middle part, the upper part and the side surface of the tea tent to the leaf apex to form water drops. No other agents were applied to control pests during the test period.
Investigation method, time and number of times: the population numbers of the worms of each test treatment and control treatment were investigated before application, and the population numbers of the worms of each test treatment and control treatment were investigated 3d and 7d after application. Randomly investigating 20 mature leaves on two sides of each row of tea trees, and counting the population of the tea lesser leafhoppers.
The drug effect calculation method comprises the following steps: the calculation formula of the population reduction rate and the control effect is as follows:
data statistical analysis: the difference of the control effect among the treatments is analyzed by adopting one-factor variance, and the difference significance of the average is compared by adopting a Duncan's new complex range method. Data calculation was done using SPSS13.0 statistical analysis software.
And (3) test results: the results of field experiments with different proportions and diluted combinations of 30% tea saponin aqueous solution and 0.3% azadirachtin emulsifiable solution are shown in table 1. The control effect of 5 proportions of tea saponin and azadirachtin and 4 dilution combinations on tea lesser leafhoppers is higher than that of a single agent of 30 percent tea saponin aqueous solution and 0.3 percent azadirachtin emulsifiable solution with the highest dilution multiple of 300 multiplied, which shows that the control effect can be obviously improved by the 30 percent tea saponin aqueous solution and the 0.3 percent azadirachtin emulsifiable solution according to 5 proportions and 4 dilution multiples set by experiments. Wherein, TAM6 (30% tea saponin aqua and 0.3% azadirachtin emulsifiable concentrate are mixed according to the ratio of 2: 1, diluted by 450 x) has the highest control effect on tea lesser leafhoppers, and the control effect is equivalent to 3000 x of a chemical pesticide of 24% chlorfenapyr suspending agent. Therefore, TAM6 was the optimal formulation and was chosen as the recommended drug for field control of tea lesser leafhoppers.
TABLE 1 prevention of tea leafhopper by different drugs (Hubei Shiweir, 5-10 months in 2019)
Example 2 field control test and Effect against tea lesser leafhoppers
The experiment of this example was carried out at tea base of institute of tea, agriculture institute of Enshi, Hubei province, and the control target was tea lesser leafhopper. The pesticide tested was the product of this invention, TAM 6. Control insecticides and concentrations were formulated as shown in table 2.
The cell arrangement and pesticide application method comprises the following steps: cell random block arrangement with cell area of 20m2Repeat 3 times. The pesticide is applied in the high-incidence period of tea lesser leafhoppers. A knapsack sprayer-duster (model: 3WF-3A) is used for uniformly spraying water on the middle part, the upper part and the side surface of the tea tent to the leaf apex to form water drops. The method of 2 applications was used. The application was carried out 7 days after the first application. No other agents were applied to control pests during the test period.
Investigation method, time and number of times: the population numbers of the worms of each test treatment and the control treatment were investigated before the application, and the population numbers of the worms of each test treatment and the control treatment were investigated 7 days after the first application and 3 days and 7 days after the second application. Randomly investigating 20 mature leaves on two sides of each row of tea trees, and counting the population of the tea lesser leafhoppers. The calculation method of the population reduction rate and the control effect and the data statistical analysis method are the same as the above.
And (3) test results: the results of the field tests are shown in Table 2. When the pesticide is applied for one time, the control effect of the product TAM6 on tea lesser leafhoppers 7 days after application is 74.19%, which is obviously higher than the control effect of 30% tea saponin aqua and 0.3% azadirachtin emulsifiable solution used independently. When the pesticide is applied for the second time, the control effect of the TAM6 on the tea lesser leafhoppers after 7 days is 88.47 percent, which is equivalent to the control effect of 1500 times of a chemical pesticide of 24 percent chlorfenapyr suspending agent.
TABLE 2 field efficacy test results for the control of tea lesser leafhoppers according to the invention (Enshi Hubei, 10 months in 2018)
Example 3 field control test and Effect for controlling tea thrips
The experiment of this example was conducted at tea base of tea research institute of the national institute of agriculture, Enshi, Hubei, and the control target was tea thrips. The tested insecticide was the product of the invention, and the control insecticide and concentration were formulated as shown in table 3.
The cell arrangement and pesticide application method comprises the following steps: cell random block arrangement with cell area of 20m2Repeat 3 times. In 6 months in 2019, the medicine is applied at the high-incidence stage of tea thrips. A knapsack sprayer-duster (model: 3WF-3A) is used for uniformly spraying water on the middle part, the upper part and the side surface of the tea tent to the leaf apex to form water drops. The application was performed 2 times, and once again 7 days after the first application. No other agents were applied to control pests during the test period.
Investigation method, time and number of times: the population base number of each test treatment and control treatment is investigated before application, and the population number of each test treatment and control treatment is investigated 15d and 21d after one application and 7d and 15d after 2 applications. Randomly investigating 20 mature leaves on two sides of each row of tea trees, and counting the insect population of the tea thrips. The calculation method of the population reduction rate and the control effect and the data statistical analysis method are the same as the above.
And (3) test results: the results of field control experiments show that the control effect of the product TAM6 of the invention on the thrips tea 21 days after application is 81.22% and is obviously higher than the control effect of 30% tea saponin aqua and 0.3% azadirachtin emulsifiable solution used independently (Table 3). When the pesticide is applied for the second time, the control effect of the TAM6 on the thrips tea for 15 days is 92.13 percent, which is equivalent to the control effect of 1500 times of a chemical pesticide of 24 percent chlorfenapyr suspending agent. Therefore, TAM6 can be used as recommended drug for preventing and treating tea thrips in tea garden by adopting a secondary drug application method.
