Problems solved by technology

[0002] Crop diseases seriously affect the yield and quality of crops. At present, there are many kinds of pesticides used to prevent and control crop diseases and insect pests, but some have single effect, some are highly toxic, and some have no obvious effect. Research and development of high-efficiency, low-toxicity, and broad-spectrum pesticides is people's pursuit.

Embodiment

[0029] Prepare 100 catties of high-efficiency, low-toxicity, broad-spectrum pesticide materials: 2 kg of plant ash, 2 catties of lime, 3 catties of cow urine, 0.5 catties of tuzet, 0.5 catties of copper sulfate, 0.6 catties of dimethoate, and the remaining water.

[0030] Its preparation method is:

[0031] 1. Copper sulfate, lime and water are first prepared into Bordeaux mixture by conventional methods;

[0032] 2. Add plant ash, cow urine, tuzet, and dimethoate into the Bordeaux mixture and mix evenly to obtain 100 catties of high-efficiency, low-toxicity, and broad-spectrum pesticides.

[0033] The use method of this pesticide is:

[0034] Foliar spraying or root drenching: use 3 catties of this pesticide per mu, mix 0.7-1 catties with 30 catties of water, spray the leaves or drench the roots on sunny days, especially when the sun is high, the effect is better.

[0035] The field comparative test of this pesticide shows that:

[0036] For rice leaf blight, use 0.7-1 cat...

Abstract

The invention discloses a high-efficiency, low-toxicity and broad-spectrum pesticide and a preparation method of the pesticide; the high-efficiency, low-toxicity and broad-spectrum pesticide is prepared by the steps of: firstly weighing 2 parts by weight of lime, 0.5 part of copper sulfate and 90-110 parts of water, evenly mixing and stirring, dissolving, filtering and removing residue to obtain Bordeaux mixture; and after that, adding 1.5-2.5 parts by weight of plant ash, 2.5-3.5 parts by weight of bovine urine, 0.5 part by weight of Tuzet and 0.6 part by weight of dimethoate into the Bordeaux mixture, and evenly mixing and stirring to obtain the pesticide. The pesticide has easily available raw materials, is low in cost and simple in preparation method; and the prepared pesticide is a systemic agent, can be used as regulator of the plants and is high in efficiency, low in toxicity, less in residue and safe to use.
