Problems solved by technology

[0003] However, lotus root will inevitably be harmed by harmful organisms in the growth process, such as root-eating golden flower worm (lotus root maggot), Spodoptera litura, apple snail, etc.
When pests broke out, lotus root farmers were unprepared and abused highly toxic and high-residue pesticides that are banned from being used on vegetables by the state, such as Temilek, Carbofuran, and Isofenphos, which made it difficult to sell the harvested poisonous lotus roots, and pesticide poisoning accidents also occurred from time to time. occur
Because the harm of these pests not only affects the yield, but also reduces the quality, which is a major factor restricting the economic benefits of lotus root and polluting the ecological environment.
At present, the special biopesticides for lotus root have not been reported yet.

Embodiment 1

[0047] Example 1 Preparation of 30% spinosad-tea saponin water dispersible granules.

[0048]In percentage by weight, spinosyn 15% (based on the weight of pure spinosyn contained in commercial goods, the same below), tea saponin 15% (the weight of pure tea saponin contained in commercial goods) Calculated, the same below), 4% sodium dodecylbenzenesulfonate, 8% dispersant NNO, 3% water-soluble starch, 8% white carbon black, and then make up to 100% with kaolin, according to the above-mentioned conventional water dispersion 30% spinosad-tea saponin water dispersible granules were prepared by the agent production process.

Embodiment 2

[0049] Example 2 Preparation of 14% spinosad-tea saponin water dispersible granules.

[0050] By weight percentage, spinosyn 2%, tea saponin 12%, washing powder 2%, pull open powder BX1%, water-soluble polycarboxylate 5%, polyvinyl alcohol 3%, white carbon black 8%, and then Make up to 100% with kaolin, and make 14% spinosad-tea saponin water-dispersible granules according to the above-mentioned conventional water-dispersible granule production process.

Embodiment 3

[0051] Example 3 Preparation of 39% spinosad-tea saponin water dispersible granules.

Abstract

The invention relates to a special biological pesticide mixture used in a lotus root field and a preparation method thereof. The biological pesticide mixture comprises the following components: ethyl spinosyn, theasaponin, a wetting agent, a dispersant, an adhesive and a carrier. The preparation method for the biological pesticide mixture comprises the steps of mixing, crushing, kneading, granulation, drying, sieving, inspection and obtainment of a finished product. The biological pesticide mixture has the advantages of high efficiency, low toxicity, low residual, an effect on controlling Donacia provosti and Prodenia litura of more than 93%, high usage security, simple and handy operation, capacity of natural degradation and good environment compatibility, thereby avoiding pesticide residual in the lotus root product; and the preparation method has the characteristics of advanced processing technology, simple and handy operation, no discharge of three wastes (waste gas, waste water and industrial residue) and high usage security.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a processing method for a biological pesticide compound preparation. Background technique [0002] my country is the origin of lotus root and has a long history of cultivation. Lotus root is rich in nutrition and delicious in taste. It is one of the necessary vegetables for people to entertain guests and in daily life. Lotus root can not only be eaten fresh, but also can be processed into lotus root powder, sugared lotus root slices, etc.; lotus seeds can be made into soup, which is a natural tonic; In the past, lotus roots were mainly planted in ponds. In recent years, with the adjustment of rural industrial structure and the development and utilization of some lake resources and wasteland resources, the production of lotus root has developed rapidly. Due to the high economic benefits of planting lotus root, some paddy fields have also developed seedling field root, which further ex...
