1. The results of the drug effects of the 7 examples and the control drug on controlling citrus red mites are as follows:
the present invention was set up with 9 treatments, examples 1-7 of the present invention, a control agent 30% Metronidazole nitrile suspension in water (Baozuo, a neutralized crop) and a blank control.
The test site is a pond town in Yuxi city of Yunnan province, the medicine is applied at the first full stage of citrus, the application time is 3 months and 14 days in 2020, and the medicine is applied once. Before and during the test, no bactericide or insecticide is applied, each treatment of the test is repeated for 3 times, the cells are randomly arranged, the area of each cell is 20m2, the manual knapsack manual sprayer is adopted for conventional spraying, the medicine is required to be uniformly and carefully applied, and the specific results are as follows:
the investigation method comprises the following steps: at least 4 red spider citrus plants are selected in each cell, and the number of red spiders on the front and back sides of each leaf is marked by each brand.
The drug effect calculation method comprises the following steps:
oral cavity decline rate (%) [ (predrug number-predrug number)/predrug number ] × 100
Control effect (%) < 1- (number of insects before application in the blank area x number of insects after application in the treatment area)/number of insects after application in the blank area x number of insects before application in the treatment area) ] × 100
The results of the field pesticide effect on controlling citrus red spiders are shown in the following table 1:
as can be seen from the table above, the effect of the pesticide of the embodiment for preventing and treating citrus red spiders is obviously better than that of a control pesticide, the control effect of the embodiment reaches about 90% in one day after the pesticide is applied, the pesticide effect is in an ascending trend along with the prolonging of time, the control effect is higher than that of the control pesticide, and the control effect can reach 100% in three days after the pesticide is applied.
2. The results of the drug effects of the 7 examples and the control drug on the prevention and treatment of soybean tetranychus urticae koch are as follows:
the invention was set up with 9 treatments, examples 1-7 in the invention; control agent 30% amitraz nitrile aqueous suspension (baozuo, a neutralized crop); and a clear water control.
The test site is Shandong Jining city Liangshan county, and the pesticide is applied once in 7 months and 18 days in 2019 at the initial stage of the soybean tetranychus urticae. Before and during the test, no bactericide or insecticide is applied, each treatment of the test is repeated for 3 times, the cells are randomly arranged, the area of each cell is 30m2, the conventional spraying is carried out by adopting a knapsack electric sprayer, the medicine is required to be uniformly and carefully applied, and the specific results are as follows:
the investigation method comprises the following steps: 5 spots per cell, 2 plants per spot, and 10 plants in total were investigated. Fixing 3, 4 and 3 leaves of each plant according to the upper, middle and lower 3 layers, respectively, investigating the number of live insects on the leaves, and calculating the reduction rate of insect population and the prevention and treatment effect.
The field efficacy results for controlling soybean tetranychus urticae are shown in table 2 below:
as can be seen from the table above, the effect of the embodiment on controlling tetranychus urticae is obviously superior to that of a control medicament, and the control effect is obvious no matter the control medicament has quick action or lasting period. Under the condition of the same content, the higher the content of the chlorfenapyr, the better the control effect is; under the condition of equal content, compared with a competitive product which contrasts with 30% of ethizole nitrile SC, the mixed control effect of the ethizole nitrile and the ivermectin is obviously higher than that of a single agent.
The effect on yield is shown in table 3 below:
as can be seen from the above table, the yield increasing effect of the examples and the control samples is significant compared to the blank control, and the yield increasing effect of the examples is significantly higher than that of the control samples. When the total content is equal, the yield increase rate of the mixed sample of the pyrazotocen and the ivermectin is higher and is respectively 29.08 percent and 23.40 percent; when the content of the pyrazotocast is equal, the higher the content of the ivermectin is, the higher the yield is; similarly, when the content of ivermectin is equal, the yield is increased when the content of the chlormequat is higher.
The ivermectin and fluxapyroxad nitrile water suspending agent developed by the invention has the advantages of obviously better control effect than a reference medicament, good quick action, longer lasting period, obvious drug effect and obvious yield increase effect. Compared with other formulations, the preparation process is simpler, the raw material sources are safer, the pesticide effect is obvious, the product stability is better, and the pesticide composition can be used for preventing and controlling crop pests such as red spider, tetranychus urticae and the like.
