Problems solved by technology

In August 2017, the harmful collembola was also found in Yongkang City, Zhejiang Province, which has serious damage to the underground bulbs of taro. According to the investigation, the damage can reach more than 40%, and the damage to the bulbs continues during the storage period, seriously affecting the production and value of taro.
[0008] At present, there is no relevant research on the use of 42.8% fludioxystrobin SC or 41.7% fluopyram SC, and adding pyrethrum extract, for repelling collembola on taro and preventing taro rot. to report

Embodiment 142

[0030] Embodiment 1 The selection of the dilution factor of 42.8% flufloxystrobin trifloxystrobin suspension concentrate

[0031] This embodiment adopts 42.8% fludioxystrobin suspension concentrate (Lunasen, Bayer Crop Technology Co., Ltd.) and 1000 times of pyrethrum extract as the control agent of taro dung collembola, 42.8% fludioxystrobin The dilution times of the suspending agent were 500 times, 1000 times, 1500 times, 2000 times, 2500 times and 3000 times respectively, and clear water was used as the control; the test site was the soil that had been harmed by collembola in Yongkang City, Zhejiang Province.

[0032] The preparation method of pyrethrum extract is as follows: take pyrethrum petals, pulverize them, weigh 1g, add 6ml of 100% n-hexane-ethanol solution, extract under reduced pressure at 40°C, and filter to obtain the extract, wherein the pressure is 70kPa.

Embodiment 3

[0044] The comparison of different medicament control effects of embodiment 3

[0045] In this example, the collembola control agent for taro was configured according to Table 3, and clear water was used as a control; the test site was the soil once harmed by collembola in Yongkang City, Zhejiang Province. The test agents mainly include: 41.7% fluopyram suspension concentrate (Lufida), 42.8% fludioxystrobin suspension concentrate, 15% indoxacarb suspension concentrate (Biaoben), 25 g / L bifenchrysin Ester EC (Uranus), 10% chlorfenapyr SC (Kamat), 3.2% Abamectin EC (Noda Qingkuai).

[0046] The test method is consistent with Example 1, and the test results are shown in Table 3.

Abstract

The invention provides a brand-new method for preventing and treating taro skin rot. A 42.8% fluopicolide-trifloxystrobin suspending agent or a 41.7% fluopyram suspending agent is mainly adopted; a pyrethrum extract is added; soil disinfection, seed taro treatment and liquid medicine root irrigation are conducted; the population density of echinococcus faecalis on taros is reduced, and therefore,the skin rot disease of the taros is prevented and treated. The method provided by the invention can prevent and treat the harm of the echinococcus faecalis on the taros in a more efficient, lower-dosage and more environment-friendly manner, reduce the occurrence of the skin rot diseases of the taros, guarantee the benefits of farmers and achieve remarkable economic, social and ecological benefits. In addition, the invention further discloses application of the 42.8% fluopicolide-trifloxystrobin suspending agent or the mixture of the 41.7% fluopyram suspending agent and the pyrethrum extract to the preparation of the echinococcus faecalis control agent for crops such as taros.

Description

Technical field [0001] The invention belongs to the field of plant diseases and insect pest control, and specifically relates to a method for preventing and controlling Echinacea faecalis on taro. Background technique [0002] Taro (Colocasia esculenta (L.) Schoot) is referred to as "taro" and is commonly known as "taro". Native to my country, India, Malaysia and other tropical areas; monocotyledonous plant, Araceae, perennial herb. The leaves are oval, the petioles are long and plump, and the flowers are yellow-green; there are fleshy bulbs underground, which are rich in starch, edible and nutritious. Its tubers contain protein 1.75-2.3%, starch 69.6-73.7%, ash 1.17-1.68%, lipids 0.47-0.68%, calcium 0.059-0.169%, phosphorus 0.113-0.274%, iron 0.0042-0.0050%, and are rich in vitamin B , B2 (riboflavin). "Southern Yunnan Materia Medica" records that taro can widen the intestines and stomach, and when swallowed, it can stimulate the appetite, open the intestines and close t...
