Description
Technical Field
The invention belongs to the technical field of pest control, and particularly relates to a method for controlling guava leaf rollers.
Background
The genus Leptospira lepidoptera (Spolotarothia) is one of the pests that endanger guava. The new tip and young fruit of guava can be endangered by the larva of the leaf roller at the whole year, female adults lay eggs on the leaf back of the new tip, the hatched larva feeds on and endangers tissue epidermis, the new leaf is spun and hung up or the leaves are hung up at one place after 3-4d, mesophyll is hidden and fed in, one worm can have a plurality of nests, the larva can also be co-used or exchanged, the larva can be pushed backwards and or spun to hang and escape when being disturbed, the old larva is loose and thin cocoons and pupated, and the phenomenon of time overlapping exists when the density is high. The damaged guava shoots stop developing, and the plant growth is greatly influenced. Besides taking fresh leaves, mature larvae can take flowers and young fruit epidermis to harm the young fruit epidermis, so that the fruit surfaces generate large brown scars and induce fruit diseases, and the commodity value and the yield of the fruits are seriously affected.
In agricultural production, the leaf rollers on guava can be prevented and controlled by spraying chemical pesticides, such as 2000 times of 50% of Du-dead-b emulsifiable concentrate, 2000 times of 40% of profenofos emulsifiable concentrate or 2000 times of 20% of high-efficiency cypermethrin aqueous emulsion and the like. Because the medicaments are repeatedly used in a large quantity, the resistance level of the leaf roller is gradually increased, so that the control effect of the conventional various medicaments on the leaf roller is gradually reduced year by year, and the resistance problem is also gradually aggravated. Therefore, the screening of the novel efficient compound agent for preventing and controlling guava leaf rollers has important significance.
The pyridalyl, also called trifluomethyl, is a high-efficiency low-toxicity insecticidal agent developed by Sumitomo chemical company, and is mainly used for preventing and controlling lepidoptera pest larvae. Studies have shown that the effect of pyridalyl is highly correlated with the inhibitory effect of insect ovarian cells. The method for compounding different pesticide varieties is a common method for preventing and controlling the agricultural diseases, the insect pests and the weeds. The screening of reasonable pesticide compounding can effectively improve the actual control effect, delay the generation of drug resistance of diseases, weeds and pests, and is an important means for comprehensive treatment of pesticides. The inventor discovers that the pyridalyl has a synergistic effect on the leaf rollers when being compounded with the acetylfipronil, the emodin or the penta-imidacloprid guanidine through researching the compounding of the pyridalyl and other pesticide varieties. At present, no report is reported on the compounding of pyridalyl and acetylfipronil, emodin or pentosan guanidine.
The information disclosed in this background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art already known to a person of ordinary skill in the art.

Preferably, the effective component II is guadipyr, and the mass ratio of the effective component I to the effective component II is 1-5:10-1.
A second object of the present invention is to provide an insecticide comprising said insecticidal composition. It is known to those skilled in the art that the selection of suitable auxiliary ingredients can be used to prepare different formulations of the insecticide given the ingredients of the insecticidal composition. Wherein the auxiliary component can be one or more selected from wetting agent, dispersing agent, filler, antifreezing agent, defoamer, disintegrating agent, solvent, binder, preservative, etc.
The third object of the invention is to provide the application of the insecticidal composition in preventing and controlling guava leaf rollers.
Finally, the invention also provides a method for preventing guava leaf rollers, which specifically comprises the following steps: spraying the pesticide every 7d for 2 times continuously; meanwhile, bagging is carried out on the guava fruits, and the bag mouth is tightly adhered to the fruit stalks, so that the damage of the guava fruits caused by the penetration of the larvae of the leaf rollers is reduced.
Compared with the prior art, the invention has the following beneficial effects:
according to the control method, the insecticidal composition is selected for foliage spraying, and meanwhile, bagging treatment is carried out on guava fruits, so that the guava leaf rollers can be effectively controlled. When the effective components in the insecticidal composition are compounded, the synergistic effect on the guava leaf rollers is achieved, compared with the single effective component, the control effect on the guava leaf rollers can be improved, the dosage of pesticides can be reduced, and the influence on the environment is reduced; in addition, the generation and development of drug resistance can be delayed, the service life of the drug is prolonged, and the integrated control of agricultural pests is facilitated.
