Registration of Main Control Agents for Cucumber Bacterial Leaf Spot
â—Ž Xiong Xingping
In the "Pesticide Registration Bulletin," "Pesticide Management Information Collection," and "China Pesticide Electronic Handbook" published by the Institute of Pesticide Verification under the Ministry of Agriculture, it was found that there are 105 effective pesticides registered for the control of cucumber bacterial leaf spot. These products play a crucial role in managing this widespread disease, which can significantly impact crop yield and quality if left unchecked.
The active ingredients included in these registrations are as follows:
1. **Thiobacillus copper** (Loncobacter) – available as a 20% SC formulation, exclusively registered by Zhejiang Longwan Chemical.
2. **Copper hydroxide** – widely registered with 73 domestic companies, making it one of the most commonly used options.
3. **Wang copper** (copper oxychloride, basic copper chloride) – registered by 20 domestic companies, offering a reliable option for disease prevention.
4. **Biclicin** – registered by 39 companies across the country, known for its broad-spectrum activity.
5. **Kasugamycin** – registered by 71 domestic enterprises, often used for its effectiveness against bacterial pathogens.
6. **Zhongshengmycin** (Kekekang) – available as a 3% WP formulation, registered by Fujian Kaili Biological Products.
7. **Agricultural Streptomycin** – registered by 26 domestic companies, commonly used for bacterial control.
8. **Copper chloride fertilizer** – registered by 19 domestic companies, combining nutrient supply with disease management.
These agents provide farmers with multiple choices depending on their specific needs, such as cost, availability, and environmental impact. It is important to follow recommended application methods and safety guidelines to ensure both efficacy and sustainability in agricultural practices.

Engine Piston Parts
The piston is one of the main moving parts of the
engine, is composed of combustion chamber components.
The pressure of the gas
piston through the connecting rod to the crankshaft, realize the change from
heat energy to mechanical energy.
The work condition is very bad, and the
temperature of 1400-1800 DEG C, and pressure
Up to 13MPa above the gas
contact, greatly alternating thermal stress and mechanical stress.
And by the
serious corrosion of gas, and under the condition of boundary lubrication and
cylinder wall friction and strong impact 1 times.
The piston in high
temperature, high pressure, strong corrosive gas contact so that it has enough
strength and hardness,
Heat resistance and good thermal resistance, high
fatigue strength and corrosion resistance. For high speed diesel Engine Piston
also requires light as far as possible.
In order to reduce the inertia
force.
Marine piston large low speed diesel engine of the crosshead is
usually combined.
The heat treatment process by normalizing and annealing,
and iron pearlite are ferrite organization, has good heat resistance.
Piston
alloy quenched and tempered steel has better heat resistance and corrosion
resistance. The skirt with nodular cast iron annealing treatment, with good wear
resistance.
