Description
Technical Field
The invention relates to an application of tetrahydropyrimidine in reducing damage of insect pests to gramineous plants, and belongs to the technical field of application of tetrahydropyrimidine.
Background
The annual grain yield is reduced by 20% -40% due to plant diseases and insect pests, and if pesticides are stopped, the grain yield can be reduced by more than one time. The annual occurrence area of crop diseases and insect pests in China is about 70-76 hundred million mu, and according to national crop disease and insect pest measurement and report network monitoring and expert consultation analysis, the crop disease and insect pests of wheat, corn, rice and other grain crops are in a resent situation. Corn is an important food crop in the world, is widely planted and is an important crop in many countries. The annual output of corn has exceeded 8.7 million tons, exceeding wheat and rice as the most abundant cereals cultivated in the world. Corn is affected by countless animals in the sowing, harvesting and storage processes, corn aphids are used as one of aphids, corn aphids are affected in the whole growth and development of the corn, and the corn yield is reduced or even prevented when the corn yield is serious.
China is one of the largest wheat producing countries in the world, and the wheat planting area and yield are always important indexes of domestic agriculture. According to statistics, the planting area of Chinese wheat in 2019 is 245 ten thousand square kilometers, the yield is 133 hundred million tons, and the yield respectively accounts for 17% and 25% of the world. Wheat aphids are one of the important pests of wheat, also called as tired or honey worms, belonging to homoptera insects. Aphids are mainly concentrated on stems, leaves, ears and other parts of the wheat, and absorb juice of the parts, so that photosynthesis of the wheat is affected, yield of the wheat is reduced, and more than 30% of loss can be caused when the aphids are serious. At present, chemical prevention and control are mainly adopted in grain crop production, so that the pesticide residue amount exceeds the standard. The pesticide residue can cause harm to the health of eaters, and serious consequences of discomfort, vomiting and diarrhea and even death can be caused when the pesticide residue is serious. The method becomes the most prominent problem in the hidden danger of food in China, and is also an important factor for restricting the export of agricultural products in China.
Tetrahydropyrimidine, chemical name 1,4,5, 6-tetrahydro-2-methyl-4-pyrimidinecarboxylic acid, also called ectoine, an amino acid derivative present in microorganisms, belongs to cyclic amino acids. Tetrahydropyrimidine was found in 1985 to originate from a microorganism (an active ingredient in highly halophiles) in salt lakes in Egypt desert areas, and therefore it is also called "halophil extract". The tetrahydropyrimidine has great application value and wide application prospect in the fields of pharmacy, food, cosmetics, biological preparations, enzyme preparations, agricultural and chemical synthetic drugs, organic electronic materials and the like. Tetrahydropyrimidine is a natural cytoprotective agent and does not pollute crops, animals and the environment.
Therefore, the tetrahydropyrimidine is introduced to reduce the damage of insect pests to gramineous plants, so that the insect pests can be reduced, pesticide residues on grains can be avoided, and the problems in the prior art are overcome.
Disclosure of Invention

Materials, reagents and the like used in the examples described below are commercially available unless otherwise specified.
Example 1: indoor test of tetrahydropyrimidine to reduce corn aphid damage to corn plants
Corn (Zhengdan 958) plants were grown in a (25 ℃ C., 14h/10 h) cultivation room and spray tests were performed with different tetrahydropyrimidine concentrations (10 ppm, 30ppm, 60ppm, 100 ppm) in the corn to trefoil, large bell mouth, and male stage, and with deionized water as a control. After spraying, corn aphids with ten days old and consistent growth conditions are inoculated on corn plants, each plant is inoculated with two fully unfolded new leaves, 10 aphids are inoculated on each new leaf, and 20 corn aphids are inoculated, wherein 5 corn plants are selected for each treatment, the number of aphids is observed for statistics on the 5 th day after inoculation, and the control effect and the feeding time occupancy of the aphids are calculated. Experiments were repeated 3 times. Control effect (%) = (control aphid number-treatment aphid number)/control aphid number x 100%, specific results are shown in table 1:
TABLE 1 corn aphid control efficacy of corn leaf blades treated at different tetrahydropyrimidine concentrations at different periods
Meanwhile, in an experiment, the EPG technology is utilized to monitor the occupancy of feeding time on phloem on corn leaves in different treatment periods after corn aphid inoculation, and specific results are shown in table 2:
TABLE 2 feeding time occupancy of corn aphids on phloem on corn leaves at different times treated with different tetrahydropyrimidine concentrations
The results in tables 1 and 2 show that the control effect on aphids and the reduction of the feeding time occupation rate of corn aphids on corn are remarkably improved in comparison with the control at the concentrations of 10ppm, 30ppm, 60ppm and 100ppm of tetrahydropyrimidine. From this, it has been shown that corn aphids can be reduced by spraying tetrahydropyrimidine, and specifically:
(1) As can be seen from Table 1, the tetrahydropyrimidine has remarkable effect on improving corn aphids in the three-leaf period, the large-horn period and the male pulling period of the corn, and the best using period and using dosage are the large-horn period and 60ppm of the corn, so that the control effect on corn aphids can reach 70.95%.
(2) As can be seen from table 2, after treatment with 60ppm tetrahydropyrimidine in the large bell mouth period, the feeding occupancy of corn aphids was as low as 6.93% which significantly reduced the feeding time of corn aphids compared to the control in the same period.
Example 2: indoor test of tetrahydropyrimidine to reduce corn aphid damage to corn plants
The test was performed in a sunlight greenhouse from the biological sciences of the Furuida, county, at 7 months 2022, and the test maize variety was Zhengdan 958. When the corn grows to the three-leaf period, the large bell mouth period and the male pulling period, selecting plant corn with consistent growth vigor and no plant diseases and insect pests, carrying out spraying treatment by using different tetrahydropyrimidine concentrations (10 ppm, 30ppm, 60ppm and 100 ppm) and contrast with deionized water, placing the corn plant in a greenhouse with corn aphid hazard after the treatment is completed for 16H, managing according to normal conditions, and observing aphid infection conditions of different treatments after 5 days. Experiments were repeated 3 times. 15 corn plants are selected for each treatment, and the aphid control effect is calculated. Control effect (%) = (control aphid number-treatment aphid number)/control aphid number x 100%, specific results are shown in table 3:
TABLE 3 corn aphid control Effect of corn leaves treated at different tetrahydropyrimidine concentrations at different periods
As can be seen from Table 3, the tetrahydropyrimidine has remarkable effect on preventing and controlling corn aphids in the three-leaf period, the large-flare period and the male-pulling period of the corn, and the best using period and using dosage are the large-flare period and 60ppm of the corn, and the preventing and controlling effect on the corn aphids reaches 75.41%.
Example 1 is that the corn plants are sprayed with the tetrahydropyrimidine to the whole corn plants when the corn plants encounter the corn aphid pest, but the example is that the whole corn plants are sprayed with the tetrahydropyrimidine before the corn plants encounter the corn aphid pest, and the data show that the spraying of the tetrahydropyrimidine before the corn aphid pest has higher control effect on the corn aphid.
Example 3: indoor test of tetrahydropyrimidine to reduce wheat aphid infestation on wheat plants
Wheat (Jimai 20) plants were planted in a culture room (25 ℃ C., 14h/10h of illumination) and spray tests were performed with different tetrahydropyrimidine concentrations (10 ppm, 30ppm, 60ppm, 100 ppm) in the jointing stage, heading stage, and flowering stage of wheat, and with deionized water as a control. After spraying, wheat plants are inoculated with wheat aphids of ten days old with consistent growth conditions, each wheat plant is inoculated with 20 wheat aphids, 5 wheat plants are selected for each treatment, the number of aphids is observed for statistics on the 7 th day after inoculation, and the control effect of the aphids is calculated. Experiments were repeated 3 times. Control effect (%) = (control aphid number-treatment aphid number)/control aphid number x 100%, body results are shown in table 4:
TABLE 4 wheat aphid control effect of wheat leaves treated at different tetrahydropyrimidine concentrations at different periods
As can be seen from Table 4, the tetrahydropyrimidine has remarkable effect on improving wheat aphids in the period of jointing, heading and flowering of wheat, and the best use period and dosage are the period of flowering of wheat and the dosage of 30ppm, and the control effect on wheat aphids can reach 71.29%.
Example 4: field test of tetrahydropyrimidine for reducing wheat aphid attack on wheat plants
The test was carried out in the temporary city of Yi-Yi city at 4 months 2023, and the test wheat variety was Jimai 20. The method comprises the steps of respectively carrying out treatments with different tetrahydropyrimidine concentrations (10 ppm, 30ppm, 60ppm and 100 ppm) in the jointing period, the heading period and the flowering period of wheat, carrying out spray tests on the treatments with deionized water, respectively investigating the aphid amount of wheat in 7 days after treatment, sampling at 5 points in each cell, investigating the continuous 10 plants of wheat at each point, investigating the residual pest amount, and calculating the control effect. Control effect (%) = (control aphid number-treatment aphid number)/control aphid number x 100%, specific results are shown in table 5:
TABLE 5 wheat aphid control effect of wheat leaves treated at different tetrahydropyrimidine concentrations at different periods
As can be seen from Table 5, the tetrahydropyrimidine has remarkable effect on improving wheat aphids in the period of jointing, heading and flowering of wheat, and the best use period and dosage are the period of flowering of wheat and the dosage of 30ppm, and the control effect on wheat aphids can reach 78.35%.
Example 3 is that the wheat plants are sprayed with the tetrahydropyrimidine on the whole wheat plants when the wheat aphids are suffered from the insect pests, but the example is that the whole wheat plants are sprayed with the tetrahydropyrimidine before the wheat plants suffer from the insect pests, and the data show that the spraying of the tetrahydropyrimidine before the wheat aphids are suffered from the insect pests has higher control effect on the wheat aphids.
In conclusion, the tetrahydropyrimidine can remarkably reduce the damage of insect pests to gramineous plants, and the control rate of corn aphids and wheat aphids reaches more than 70%; meanwhile, the tetrahydropyrimidine is a natural cell protectant, does not pollute crops, animals and the environment, meets the use requirement of reducing the damage of insect pests to gramineous plants, is truly green and healthy, and is harmless to human beings and the environment.
