Description
Technical Field
The invention relates to the technical field of vegetable disease control, in particular to a winged pest control agent composition for fruits and vegetables planted in a greenhouse, a pest sticking plate and a control method; is especially suitable for greenhouse fruits and vegetables in summer and autumn, such as grapes, tomatoes, cucumbers and the like.
Background
With the improvement of living standard of people, the demand and purchase of fruits and vegetables are not limited to seasons any more, the off-season fruit and vegetable market is larger and larger, and the planting of the off-season fruits and vegetables is more and more popular with farmers. The anti-season fruit and vegetable planting method generally adopts a greenhouse planting mode, and achieves the purpose of enabling fruits and vegetables to grow by artificially controlling the growth conditions in a greenhouse. Although the greenhouse planted fruits and vegetables have wide market prospect, the investment cost and the management cost are high, so that the risk born by farmers is also large. Wherein pest control is a big problem in the greenhouse planting process. At present, the simplest and most effective mode for preventing and treating insect pests is to apply pesticides, but as the requirements of people on food health are higher and higher, the organic environment-friendly planting mode is more popular.
For example, one of the main pests damaging grapes is thrips, the peak period of thrips occurrence is two periods of 5-6 ten days and 8-10 months, wherein 8-10 months are in late summer and early autumn and are in high temperature end period, the temperature difference between day and night is large, the environment humidity is large, and the pest and disease damage propagation is very suitable, so that the difficulty in controlling thrips in summer and autumn is higher.
The main pests damaging the tomatoes are whiteflies and thrips. The tomatoes are very popular fruits and vegetables on dining tables of people, have fresh, cool, sour and sweet mouthfeel, rich nutrition and very large market demand, and have very good planting prospects. Generally, tomatoes are planted in summer, but in order to meet market demands, a large number of planters plant autumn tomatoes in greenhouses. However, in the late stage of positive high temperature during the planting period of autumn tomatoes, the temperature difference between day and night is large, the relative humidity is also large, and the environment is very suitable for breeding of plant diseases and insect pests, especially winged pests. Is particularly easy to appear in the greenhouse in the evening, thereby harming the growth and development of the tomatoes.
At present, various prevention and control medicaments on the market are full of precious and good in pesticide effect aiming at various pests, but the existing prevention and control methods are that medicaments are directly sprayed on plants, so that the pests can be effectively prevented, but medicament residues are easily caused, and the human health is harmed. The completely green and environment-friendly pest control method is time-consuming and labor-consuming, has poor effect and cannot meet the market demand.

Note: the above statistical result was 1dm from the middle of each side of each selected armyworm plate2The number statistics is carried out on the regions, and then the average value of the front side and the back side is taken; the control example used a commercially available single-sided single-layer conventional armyworm plate.
In order to further verify the effect of the insecticidal synergist, the invention designs a comparative example 5, which is different from the example 4 only in that no insecticidal synergist is added, the same test is carried out in another greenhouse with the same specification, and then insect density statistics are carried out, wherein the statistical result is 41 insects/dm2。
To further verify the effect of the repellent, the invention designs a comparative example 6, which is different from the example 4 only in that the repellent is not used, the same test is carried out in another greenhouse with the same specification, and then pest density statistics is carried out, wherein the statistical result is 31 pests/dm2。
To verify the effect of the addition of zeolite powder on the insecticidal time, comparative experiments were performed in this application. To simplify the test, the armyworm plates were covered on the back side in the following test, leaving only the front side, i.e. as a single-layer armyworm plate. The armyworm plates of example 4 and comparative example 5 were hung in transparent boxes, recorded as box a and box B; whiteflies were placed into both boxes simultaneously and the time to death recorded for each was averaged, resulting in an average time to death of 5.6s in case a and 9.8s in case B. (when the whitefly is observed to be completely immobilized, the whitefly is judged to be dead, and the death time is the death time from the moment the whitefly is put into the reactor to the death time), so that the death of the whitefly is accelerated by adding the zeolite powder, and the exerting speed of the active ingredients of the medicament is improved.
In order to compare the insecticidal effects of the sticky boards of example 4 and comparative example 5 after the decrease of the sticky effect, the sticky boards of example 4 and comparative example 5 were placed in the same outdoor condition at the same time, placed in the box A and the box B respectively after 48 hours, then 5 whiteflies were placed at the same time, the death time of each was recorded and averaged, and the result showed that the average death time in the box A was 6.7s and the average death time in the box B was 15.4s, and it was found that even if the adhesive viscosity of the adhesive was decreased after the agent was loaded with the zeolite powder, the effect on the efficacy of the active ingredient of the agent was not so great. However, the adhesive viscosity of the insect sticking plate without zeolite powder loading is reduced, and whiteflies can die after contacting the insect sticking plate for many times, so that the insecticidal effect is greatly reduced.
The above-described embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the technical solutions of the present invention can be made by those skilled in the art without departing from the spirit of the present invention, and the technical solutions of the present invention are within the scope of the present invention defined by the claims.
