In recent years, in order to solve the pest resistance, or to achieve the purpose of simultaneous treatment of several diseases and insect pests at one time, pesticides are becoming more and more common, but the dilution of mixed pesticides is a matter of technology.

Determine the amount of liquid spray per hectare should be based on the types of crops, growth potential, land area, the type of spray technology used, the types of pests and weeds and other factors to determine the appropriate amount of spray liquid. Generally use constant spray, spraying 750 ~ 1500 kilograms of liquid per hectare.

Correct control of effective dose per hectare For a single agent, the effective dose per hectare is generally: 750 grams of insecticide, 1500 grams of fungicide, and 3000 grams of herbicide. In recent years, some effective insecticides such as pyrethroids, abamectin, etc. have been developed. The effective dose per hectare is only 12-75 grams. For compounded applications, the total effective dose per hectare should not exceed the above criteria in principle. The formula is as follows:

Applying amount per hectare = spraying amount per hectare / dilution of Pesticide. Total effective dose per hectare = A pesticide applied per hectare Effective dose + B pesticide applied per hectare Effective dose + C pesticide applied effective dose per hectare.

For example, 50% carbendazim 600 times solution + 70% thiophanates 800 times solution +12.5% ​​rilicon 2000 times solution can be used to control stalk whitish blight or wilt disease. The dosage of 850 should be mixed per hectare. kilogram. How to prepare? The dosage per hectare for each agent was: carbendazim = 850/600 = 1.4167 kg, thiophanates = 850/800 = 1.0625 kg, and dipole = 850/2000 = 0.425 kg. The total effective drug dose per hectare is 1.41670.5+1.06250.7+0.4250.125=1.5052 (kg), which is in line with the standard for the effective dose of fungicides per hectare. Can be measured separately 50% carbendazim 1.4167 kilograms, 70% thiophanate-methyl 1.0625 kg and 12.5% ​​enemy force Kang 0.425 kg, using two-step dilution method, 850 kg of water, spray after mixing.

Cucumber

Netherlands cucumber for female is more, mainly for greenhouse cultivation, unlike most outdoor cultivated varieties, they can not through pollination fertilization can finish the development of the fruit, but does not form a fully developed seeds.Early female system has the advantage of fruit maturity, high yield.The characteristics of this type of melon is: melon, one section one melon, section 1, 2 and more than 1 section melon melon.And, if appropriate management level, high yield potential is very big, 667 square meters of single crop yield can be over 10000 kg.1 year can be 2-3 times.
