Biological pesticidal and sterilizing composition and production method thereof

Abstract

The invention discloses a biological pesticidal and sterilizing composition containing validamycin A and avermectin and a production method thereof. The composition comprises the following effective components: 2-20% of validamycin A and 1-5% of avermectin. The production method is realized by the following steps: adding the raw materials into an enamel stirred tank, evenly mixing, and pulverizingby air flows or milling to obtain the biological pesticidal and sterilizing composition containing validamycin A and avermectin, which is in the state of the wettable powder or suspending agent. Since the validamycin A and the avermectin are compounded for use, the composition has the characteristics of low toxicity, low residue, wide pesticidal range, favorable lasting effect, low cost and especially biological prevention and control capability without environmental disruption, and thereby being an ideal biological pesticide for preventing and controlling various plant diseases and insect pests of rice.

Description

technical field

[0001] The invention relates to the technical field of pesticide production, in particular to the technical field of pesticides for controlling various diseases and insect pests of rice. Background technique

[0002] Rice diseases and insect pests are an important cause of damage to rice production, and realizing pollution-free biological control of rice diseases and insect pests is the development direction and goal of the field of agricultural plant protection. In recent years, although the state has explicitly banned the use of highly toxic pesticides on rice, it is still common to use highly toxic and high-residue pesticides in the actual agricultural production process due to the lack of efficient pest control agents. Therefore, research and development of high-efficiency, low-toxic, Low-residue new biopesticides are an inevitable development trend.

Embodiment 1

[0017] Embodiment 1 produces 10% Jinggangmycin Abamectin wettable powder pesticide product

[0018] Weigh the materials according to the following weight ratios:

[0019] Jinggangmycin 8.5%

[0020] Abamectin 1.5%

[0021] NNO (dispersant) 3%

[0022] Sodium lignosulfonate (dispersant) 7%

[0023] Sodium alkylbenzene sulfonate (dispersant) 1%

[0024] White carbon black (filler) 79%

[0025] Add each material in turn under stirring, after being pulverized by an airflow mill and then stirred and mixed evenly, the product is obtained, and the field efficacy test of controlling rice stem borer and sheath blight is carried out. The drug effect is good, and the control effect on rice stem borer is at More than 85%, the control effect on rice sheath blight is 80%.
