Technical Field

The invention relates to the technical field of pesticide application range, in particular to application of a pesticide taking buprofezin as an effective component in controlling tussah garden pests in tussah production.

Background

The oak leaves are the most favorite feed for tussah. The tussah is a wild silkworm with important economic value, and the growth and development stage of the larva of the tussah is completed on the tussah in a tussah garden. Under the condition of wild natural environment, the pests in the tussah garden (tussah pests and oak tree pests) pose serious threats to the normal growth and development of the tussahs, such as: the method is characterized in that predatory pests such as black broad shoulder ambulation, concave-wing wide-jaw ambulation, lygus bugs, arma bugs, long-horned grasshopper, green Yaxing ambulation, four-star burial insects and the like attack on the tussahs, and phytophagous tussah pests compete for tussah leaves with the tussahs, so that the normal production of the tussahs and the yield of tussah cocoons are seriously influenced. The tussah is very sensitive to pesticide, and in the tussah garden, except for the dimethoate, the conventional pesticide is adopted, so that the poisoning and death of the tussah can be directly caused frequently, but the pests in the tussah garden still survive. The chemical pesticide powder is applied to the ground of the tussah garden to prevent and control the black broad-shoulder chafers and the longhorned grasshopper, so that higher pesticide residue and ecological environment pollution risk exist. At present, the pesticide is safe to tussah and lacks of efficient chemical control means for tussah garden pests. Therefore, how to avoid poisoning or influencing the normal growth and development of the tussah while effectively preventing and controlling the pest in the tussah garden is one of the key points and difficulties of the current tussah protection science research.

Buprofezin, the English name, belongs to insect molting inhibitors. Buprofezin is highly effective against hemipteran pests and not effective against lepidopterans. Has persistent larvicidal activity against Coleoptera, partial Homoptera and Acarina. By inhibiting chitin synthesis and interfering metabolism, pests can not normally molt and metamorphose and die gradually. Has the characteristics of high activity, high selectivity and long residual period. At present, most of researches on buprofezin are applied to pest control in plant culture as an insecticide, but no relevant research report exists on the buprofezin is used as an active ingredient alone or a compound pesticide used in tussah production.

。

As can be seen from Table 1, the different combinations of insecticides all had better control effect. The components of the pesticide have good prevention and control effects on the black shoulder beetles according to the mixture ratio range in claim 1.

Example 2 Oak gardens were used to control female-wing broad-jaw Artocarpus larvae.

The test was carried out in an oak garden in Xiuyan county, Anshan city, Liaoning province. The test was performed with 1 dose in the afternoon during the peak occurrence period (8 months and 8 days) of the low-age nymphs of the concave-wing broad-jawed beetles. The components of the medicament are respectively A, AB, AC, AD, AE, AF, ABC and the dosage of buprofezin in 15L water is 0.35 g-15.0 g. Uniformly spraying by using a knapsack manual sprayer, wherein the oak mainly comprises female-wing broad-jaw larva of the Artocarpus communis, a small amount of Artocarpus heterophyllus, lygus, Arcolimus chinensis and longhorned grasshopper adult, the pesticide application day is cloudy, and the average temperature is 29.5 ℃; no rain was found in 2 days after the application. And investigating the prevention and control effect for 24 h. And (4) carrying out statistical calculation on the correction control effect according to a conventional experimental method.

TABLE 2 field control Effect of Buprofezin and combination pesticide on concave-wing Arthropoda-Spinosa larvae

。

As can be seen from Table 2, the different combinations of insecticides all had better control effect. The components of the pesticide have better prevention and control effects on the larva of the concave-fin wide-jaw larva according to the proportioning range in claim 1.

Example 3 Oak Garden is used for preventing and controlling Artocarpus nigra, Ordosis similis and longhorned grasshopper.

In an tussah silkworm field in Xiuyan county of Anhui mountain city, Liaoning province, the buprofezin A and the combination of the buprofezin B, dimethoate C, D malathion, E-methylpyrimidin and F-sulfoxaflor in different proportions are tested for the prevention and control effects of the buprofezin A, the trianghi and the longhorned grasshopper of the tussah silkworm, and the using dose of the buprofezin in 15L water is 0.35 g-15.0 g. The above 3 components were processed in the proportions shown in Table 2, and the test methods were the same as in example 1.

TABLE 3 field control effect of buprofezin and combined pesticide on Bupleurum bughizus, Oridous, and longhorned grasshopper

。

As can be seen from Table 3, buprofezin A and the combination thereof with B, C, D, E, F in different proportions have better prevention and control effects on the broad shoulder ambaris, the lygus lucorum and the long-horned grasshopper in the field. The buprofezin is used alone and compounded and combined with other pesticides, and has ideal prevention and control effects on the pests.

Example 4 buprofezin is tested for tussah safety.

A buprofezin A and a combination of buprofezin B, dimethoate C, malathion D, pirimiphos-methyl E and flonicamid F in different proportions are tested in a tussah silkworm farm in Xiuyan county of Anshan city of Liaoning province, the safety test on the tussah silkworms is tested, the tussah silkworms on the tussah trees are 1-instar larvae, and the number of the heads of the tested tussah silkworms is 100. Uniformly spraying by using a knapsack manual sprayer, wherein the using dose of the buprofezin in 15L of water is 0.35-30 g, the application day is sunny, and the average temperature is 31 ℃; there was no rain after 3 days. After 72 h, the number of tussah heads showing poisoning symptoms (body curls into C shape or S shape, spasm, liquid regurgitation, food refusal, molt, loss of silkworm grip, hanging upside down on tussah branches, etc.) was investigated.

TABLE 4 evaluation of the safety of buprofezin and the combined pesticide to 1 st tussah larva

。

As can be seen from the table 4, when the safety test of the buprofezin alone and the buprofezin B, C, D, E, F combined with tussah in the field evaluates that the use concentration of the buprofezin does not exceed 1 g/L, no poisoning of the tussah is found, and the buprofezin is safe to the tussah. Only when the concentration of buprofezin reaches 2 g/L, 1 tussah silkworm shows the poisoning symptom of abnormal molting.

In conclusion of the results of the wild test in the tussah garden, the insecticidal composition prepared by taking buprofezin as an active ingredient and binary or ternary compounding of the buprofezin has better control effect on pests such as concave-fin broad-jaw stephania, black broad-shoulder stephania and the like. When the using concentration is not more than 1 g/L, the tussah is safe. The buprofezin provided by the invention has the advantages of unique action mechanism, good quick-acting performance and tussah safety when the use concentration is not more than 1 g/L, so that the buprofezin has great economic value in subsequent research, development and popularization and application, and has very important significance in increasing the yield and income of stockbreeding tussah farmers and protecting ecological environment of tussah gardens.
