Butadisulfide is a kind of carbamate insecticide . It is suitable for crops such as citrus, rice, vegetables, apples, pear trees, etc. It is often used to control aphids, leaf miners, and thrips. Rice cockroaches and underground pests, let us first understand the method of controlling mites in the sulphur.
1. Prevention and control of orange mites In the spring shoot period, citrus blooms and young fruit, aphids are the main pests. Applying in the aphid stage, spraying with 20% emulsifiable concentrate 1000-1500 times or every 100 liters of water plus 20% good winter 66.7-100 ml (effective concentration 133.3-200 mg/L) can effectively prevent mites and can Decrease the number of rust spiders.
2, prevention and control of vegetable aphids, leaf miner with 20% EC milk 60 ~ 100 ml (active ingredient 12 ~ 20 grams) plus water 30 ~ 50 liters spray can control the thrips. Use 40% to 50ml of 20% emulsifiable concentrate (8-10g of active ingredient) and 30~50 liters of water per acre to control vegetable leaf miner.
3, prevention and treatment of apple jaundice with 20% emulsifiable concentrate 2500 ~ 3500 times liquid or 20% per acre with good winter 28.5 ~ 40 ml (effective concentration of 57 ~ 80 mg / liter) in the new shoots prosperous growth period can control apple jaundice; 20% EC 1500 ~ 2000 times liquid or 20% per 100 liters of water plus 50 ~ 66.7 ml (effective concentration 100 ~ 133 mg / liter) can control apple mites, tumor mites, and metallurgical moths.
4, prevention and control of pear tree birch, yellow meal mites with 20% EC 2000-3000 times liquid per 100 liters of water plus 20% good winter 33 ~ 50 ml (effective concentration of 67 ~ 100 mg / liter) spray.
5, the prevention and control of wheat aphid in the period of 20% per year, 20 to 50 ml of good winter emulsifiable concentrate (active ingredient 6 to 10 grams) spray 30 to 50 liters of water.
6. Control the occurrence of rice planthoppers. Use 20% of good winter emulsifiable concentrate per acre (30 grams of active ingredient) and spray 30 to 50 liters of water.

A solar inverter or PV inverter, is a type of electrical converter which converts the variable direct current (DC) output of a photovoltaic (PV) solar panel into a utility frequency alternating current (AC) that can be fed into a commercial electrical grid or used by a local, off-grid electrical network. It is a critical balance of system (BOS)–component in a photovoltaic system, allowing the use of ordinary AC-powered equipment. Solar power inverters have special functions adapted for use with photovoltaic arrays, including maximum power point tracking and anti-islanding protection.
Solar inverters may be classified into four broad types:
Stand-alone inverters, used in isolated systems where the inverter draws its DC energy from batteries charged by photovoltaic arrays. Many stand-alone inverters also incorporate integral battery chargers to replenish the battery from an AC source, when available. Normally these do not interface in any way with the utility grid, and as such, are not required to have anti-islanding protection.
Grid-tie inverters, which match phase with a utility-supplied sine wave. Grid-tie inverters are designed to shut down automatically upon loss of utility supply, for safety reasons. They do not provide backup power during utility outages.
Battery backup inverters, are special inverters which are designed to draw energy from a battery, manage the battery charge via an onboard charger, and export excess energy to the utility grid. These inverters are capable of supplying AC energy to selected loads during a utility outage, and are required to have anti-islanding protection.
Intelligent hybrid inverters, manage photovoltaic array, battery storage and utility grid, which are all coupled directly to the unit. These modern all-in-one systems are usually highly versatile and can be used for grid-tie, stand-alone or backup applications but their primary function is self-consumption with the use of storage.
