Non-toxic fruit and vegetable disease-resistant insect-resist agent

Abstract

The invention discloses a non-toxic fruit and vegetable disease-resistant insect-resist agent, which is characterized in that extracts prepared from lettuces, peppers, onions, garlics and isatis roots by a quantum extraction method or a low-temperature supercritical fluid extraction method are prepared from the following raw materials in percentage by weight: 10 to 70 percent of lettuce extracts, 5 to 15 percent of pepper extracts, 10 to 20 percent of onion extracts, 5 to 25 percent of garlic extracts, 5 to 15 percent of pepper extracts and 5 to 15 percent of isatis root extracts. The substances are mixed. In the use process, water is added into the concentration liquid for diluting 20 to 50 times; the disease-resistant insect-resist spray agent can be obtained. When the agent is sprayed onto the surfaces of vegetables, melons and fruit, the pest invasion can be prevented; existing pests can escape and evade, so that the crops are protected from plant diseases and insect pests; the occurrence of various diseases can also be prevented and treated; the yield and the eating safety of vegetables and fruit can be ensured.

Description

technical field [0001] The invention relates to a non-toxic anti-disease and insect-repelling agent for fruits and vegetables, which belongs to the field of new technologies for planting insects and insects in crops, and in particular to a disease-resistant and insect-resistant vegetable, melon, and fruit prepared by extracting active ingredients from non-toxic and harmless plants and Chinese herbal medicines by using high technology. agent. Background technique [0002] In the past, chemical pesticides that are toxic and harmful to the human body were used in the cultivation of vegetables, melons and fruits. Long-term consumption of vegetables and fruits containing chemical pesticides and drinking water polluted by chemical pesticides have caused more and more cancer patients. The age at which cancer appears is also getting younger. At the same time, because the pesticide residue exceeds the standard, it also affects the export of agricultural and sideline products.
