Embodiment 1

[0110] A representative composition of a colloidal formulation is given below:

[0111] Natural polymer polysaccharide insecticidal colloid preparation

[0112] Component Source or trade name %w / w

[0113] Konjac Glucomannan KG90TT1220 10

[0114] Cactus Juice Homemade 10

[0115] Alkyl polyglycoside AL2042 15

[0116] Natural plant mixed fatty acid esters Oil factory waste 20

[0117] Add water to all the above components to make up to 100%, and make an oily transparent liquid colloid after stirring. The ready-made product (this product is named "crop health shower gel") is diluted 200-1000 times with water and sprayed on plant leaves. It can kill aphids, red spiders, whiteflies, adult leaf miners, wind butterflies, poisonous moths, crickets, mole crickets and other young larvae or nymphs. See Table 1 for specific effect data.

[0118] The contents of the substances in the formula can be adjusted appropriately according to the ranges of the aforementioned components, ...

Embodiment 2

[0120] components source or trade name %w / w

[0121] Konjac Glucomannan KG90TT1220 40

[0122] Cactus Juice Homemade 40

[0123] Alkyl polyglycoside AL2042 50

[0124] Coconut oil diethanolamide Commercially available 60

[0125] Sucrose or glucose Commercially available 10

[0126] water 200

[0127] Mix the above components, stir well, and make a viscous colloid, dilute 200-800 times with this product (dissolve it with a small amount of water first, then add a sufficient amount of water to mix well) and spray on it. The branches and leaves of crops have the effect of eradicating aphids and mites, and at the same time can resist the conidia of various germs from infecting crops, achieving the effect of treating both diseases and insect pests. See Table 2 for performance data.

Embodiment 3

[0129] Soluble Granule Formulation 1

[0130] components source or trade name Weight (kg)

[0131] Konjac Glucomannan KG90TT1220 100

[0132] Cactus Juice Homemade 100

[0133] Alkyl polyglycoside ATPLUS258 50

[0134] Sucrose or glucose Commercially available 20

[0135] Mix the above raw materials evenly, and pulverize them with an airflow mill (AD turbine mill, Shengzhou Zhedong Pulverizer Factory) to obtain mother powder with a fineness of 900-1000 mesh, mix and stir the mother powder with 30kg of water evenly, and then Sent to the granulator (flat twin-screw extruder, Changzhou Fafa Machinery Equipment Factory) to extrude and granulate to obtain columnar granules, and then put the wet columnar granules into a rounding machine (JPY-2 type, Shandong Tengzhou Lu (Shanghai Machinery Co., Ltd.) was thrown round, and the rotating speed was 700 rpm, and then sieving, drying, and re-sieving to obtain uniform diameters were 1.2cm circular soluble granules, and the gran...

Abstract

The invention relates to a natural high polymer polysaccharide insecticidal composition, which belongs to a highly-efficient, non-toxic, residual-free and pollution-free environmentally-friendly plant-source insecticidal composition special for the prevention and control of harmful insects and diseases of crops. The composition contains konjac glucomannan, cactus juice and alkyl polyglycosides, can control a plurality of diseases and the breeding of the harmful insects after being applied to the leaves of crop plants, suffocate a plurality of harmful insects or non-anaerobic germs due to anoxia and stick the limbs and wings of the plurality of harmful insects to make the harmful insects inconvenient to move and kill the harmful insects, is extremely easy to degrade, broad in insecticidal spectrum and low in cost, and can achieve a rooting effect particularly in the prevention and control of mite insects. Due to the adoption of a physical mechanism of body contact killing, the resistance of prevented and controlled objects to pesticides is difficult to produce. The composition also can be used as one of a plurality of environmentally-friendly pesticide synergist agents, does not produce chemical injuries to the crops, and can promote the theoretical growth of the crops, improve the quality, increase the yield and achieve remarkable effects.

Description

technical field [0001] The invention relates to an insecticidal composition mainly composed of natural polymer polysaccharides and a preparation method thereof. Specifically, the composition contains: konjac glucomannan, cactus juice and alkyl polyglucoside. Background technique [0002] At present, the control of agricultural pests and diseases is still dominated by chemical pesticides, but it is the trend of the development of pesticides in the world to use high-efficiency, low-toxic, safe and environmentally friendly methods to prevent and control pests and diseases. [0003] Konjac glucomannan has many properties such as good hydrophilicity, gelling property, film-forming property, antibacterial property and edible property, and is widely used in the fields of food, medicine, chemical industry and biology. In the field of pesticides, there have been reports on the application of fruit preservatives, mainly utilizing its antibacterial properties; CN1361091A discloses a m...
