Effect test

experiment example 1

[0024] Experimental example 1 (indoor test)

[0025] Get 0.2ml of the medicament of Example 1, mix evenly with the rice treated with 1000g of pests by spraying method, put it into a 1000ml wide-mouth bottle, and put corn weevil, corn beetle, rusty red flat beetle and red pseudograss into each bottle separately More than 35 pigs were placed in an incubator (temperature 28±2°C, humidity RH75±5), and the mortality rate was measured after 15 days. Parallel groups and blank controls were set up. The test showed that the corrected mortality of the four stored grain pests was 100% after 7 days.

experiment example 2

[0026] Experimental example 2 (medium-scale test)

[0027] The spray method is used on the belt conveyor. Take each 1000ml of Examples 1-4 as the experimental group, mix them with 5 tons of paddy evenly, adopt encirclement and loose release, set up four repetitions, randomly arrange piles, and set up a control group, the test results are shown in Table 2:

[0028] Table 2

[0029]

[0030] Experimental example 1 (Okura test)

[0031] Taking Example 1 as the experimental medicament, using sepiolite as the carrier, adopting the carrier method, spraying the grain heap surface layer, about every 1000m 2 The granary uses 100kg of chemicals and mixes them evenly. The test results are shown in Table 3:

[0032] table 3

experiment example 4

[0034] Experimental example 4 (mildew proof test)

[0035] Get water and be 200kg of early indica rice of 16%, wherein 100kg paddy is applied the present invention (embodiment 1) 10ml with direct spraying method, mixes evenly, and another 100kg is used as blank control, packs with sack respectively, tie tightly, puts under normal temperature. Check for mold damage after 30 days. The grain of the control group not using the present invention obviously had a musty smell, the rate of mildew was 36%, and the loss due to mildew was 14%. The grain smell of the treatment group of the present invention is basically normal, the mildew rate is only 1.2%, and the mildew loss is 0.4%.

Abstract

The invention discloses a green insect-and-mildew inhibitor for grain storage. The insect-and-mildew inhibitor comprises the following components, by mass: 4-10% of dihydrosterculic acid, 8-15% of dioxo-phenyl-diguanidino-hexane, 1-5% of arctiin, 69-86.5% of dimethyl carbonate, and 0.5-1% of emamectin benzoate. The green insect-and-mildew inhibitor for grain storage can effectively prevent common pests, such as corn weevil, angoumois grain moth, oryzaephilus surinamensis, and cryptolestes ferrugineus, of grain storage, and can inhibit grain moulding, so that mildew loss of grain storage is reduced. The insect-and-mildew inhibitor is green and safe, is free of peculiar smell and residue, and is low in cost. The insect-and-mildew inhibitor is suitable for application to prevention of insects and mildew of grain storage.

Description

technical field [0001] The invention belongs to medicine for grain storage, and in particular relates to a green grain storage insect-proof and mildew-proof agent and a preparation method thereof. Background technique [0002] my country is the largest grain production and consumption country in the world, and the safety of grain storage is related to the national economy and the people's livelihood. According to statistics, subject to storage conditions and storage technology, my country's annual grain loss due to insects and molds exceeds 6 million tons. Phosphine fumigation is mainly used in the prevention and control of stored grain pests in the treasury. Because phosphine has teratogenic and carcinogenic side effects and serious 3R problems, it will soon be eliminated. In rural areas, there is no suitable pest control agent, and most farmers are helpless against the rampant pests, resulting in serious food losses. Some farmers use highly toxic pesticides, causing huma...
