1. It should be used with the equipment. The water temperature of the stone sulphur mixture should be lower than 30 °C, and the hot water will reduce the effectiveness. Temperatures above 38 ° C or below 4 ° C can not be used. The temperature is high and the effect is good. When the temperature reaches 32 °C or above, use it with caution. The dilution factor should be increased to more than 1000 times. The safe use interval is 7 days.
2. Avoid mixing with Bordeaux mixture, copper preparation, mechanical emulsifiable concentrate, rosin mixture and pesticides that are easily decomposed under alkaline conditions. When used in tandem with the Bordeaux mixture, there must be sufficient intervals. First, spray the sulphur mixture, and spray the Bordeaux mixture after 10~15 days. If the Bordeaux mixture is sprayed first, it is necessary to spray the stone sulfur mixture after 20 days.
3, avoid blind application, crops sensitive to stone sulphur mixture, easy to cause phytotoxicity, should be tested or in accordance with the guidance of the local agricultural technical department. Rosaceae plants such as peach, plum, plum, pear, etc., and leguminous plants such as Bauhinia and Acacia are sensitive to stone sulfur mixture, and should be used with caution during the growing season and flowering. It can be used at a reduced concentration or during dormancy to avoid phytotoxicity. For example, Li Shu spraying stone sulphur mixture will inhibit flower bud differentiation, resulting in lower yields next year.
Master the timing of use. The best period for the use of fungicide stone sulphur mixture is in the dormant period of trees and before germination in early spring. In the apple orchard where red spiders occur, when the damage to the leaves is very serious, it is not advisable to spray the sulphur mixture to avoid causing the leaves to dry up and fall off.
4. The concentration of the stone sulphur mixture is determined according to the climatic conditions and the period of prevention and treatment. In winter, the temperature is low, the plants are in a dormant state, and the concentration can be higher; in summer, the temperature is high, the plants are in a vigorous growth period, and the use concentration is low. Excessive concentration or excessive temperature may cause phytotoxicity. The tree and flower dormancy period (early spring or winter) is high in spraying concentration and low in growing season. Under normal circumstances, the concentration of the stone sulphur mixture is 3 to 5 degrees in the dormant period of the deciduous fruit tree; 0.1 to 0.2 degrees in the vigorous growth period is appropriate.
5, protective clothing should be worn when dispensing and applying, and the whole body should be cleaned after spraying. When cleaning the sprayer, do not allow the wastewater to contaminate the water source. The liquid splashes on the skin and can be washed with plenty of water to prevent skin burns. The sprayer after applying the stone sulphur mixture must be thoroughly washed to avoid corrosion damage.
6, fully stir before use, long-term continuous use is easy to produce phytotoxicity, should be used interchangeably with other pesticides .
Car engines are designed around sealed, resilient metal cylinders. Most modern vehicles have between four and eight cylinders, though some vehicles can have as many as sixteen! The cylinders are made to open and close at precisely the correct time to bring in fuel to combine with the spark for burning internally, and to release the exhaust gases produced. While there are several components on an engine, we`ve compiled a list of the most essential car engine parts and their functions, that power your vehicle. Refer to the diagram to locate where they reside on your engine.
Engine valve – This is the very core of the engine. Often made of aluminum or iron, it has several holes to contain the cylinders as well as provide water and oil flow paths to cool and lubricate the engine. Oil paths are narrower than the water flow paths. The engine block also houses the pistons, crankshaft, camshaft, and between four and twelve cylinders-depending on the vehicle, in a line, also known as inline, flat or in the shape of a V.
Pistons – Are a cylindrical apparatus with a flat surface on top. The role of the Piston is to transfer energy created from combustion to the crankshaft to propel the vehicle. Pistons travel up and down within the cylinder twice during each rotation of the crankshaft. Pistons on engines that rotate at 1250 RPM, will travel up and down 2500 times per minute. Inside the piston, lie piston rings that are made to help create compression and reduce the friction from the constant rubbing of the cylinder.
Timing Belt/Chain – The camshaft and crankshafts are synchronized to ensure the precise timing in order for the engine to run properly. The belt is made of a heavy-duty rubber with cogs to grasp the pulleys from the camshaft and crankshaft. The chain, similar to your bicycle chain wraps around pulleys with teeth.
