Additional crop control judgment method by pesticides}

The present invention relates to a method for determining crop additional drug control.

Damages caused by pests and diseases of crops are continuously raised, and chemicals are sprayed to prevent them.

Blights and pests are mostly related to temperature and humidity, and crops suffer great losses due to pests and diseases.

However, if the drug is sprayed periodically, the spray amount of the drug cannot be efficiently controlled, so the drug is sprayed excessively, causing environmental pollution and cost of the drug. There is a problem in that a lot of time and money are consumed in eradicating pests.

Even at the time when pests and diseases easily occur due to temperature and humidity, considering that pests and diseases can be prevented and eliminated by timely spraying of pesticides on crops, it is important to determine the timing of spraying chemicals to prevent loss of crops. This is a very important issue.

Conventionally, in addition to the above-mentioned periodic spraying of the drug, there is awareness of spraying the drug by utilizing weather information including temperature and humidity at the current time.

However, conventionally, there was a lack of awareness of additional spraying of the drug in consideration of the residual drug efficacy of the drug at the current time after spraying the drug, and it was washed away by precipitation according to the precipitation information as well as the temperature and humidity before and after the current time. Considering the degree of outgoing, awareness of additional spraying of the drug was lacking. Accordingly, there is a problem of excessive spraying of drugs without accurately considering the residual drug efficacy of the current time, and it is difficult to efficiently control the drug because the drugs are not timely controlled according to the residual drug efficacy.

Referring to Figure 1, the method according to the present invention will be roughly described.

Time information including a current time and a current date is input to the information collection unit 100 .

The information collection unit 100 may receive weather information in real time or upon request from a system in which weather information is stored, such as a database of the Korea Meteorological Administration.

Meteorological information including daily average temperature and precipitation from a preset date to the current date is input to the information collection unit 100 .

In addition, the information collection unit 100 may further input information on spraying including a spraying time closest to the current time of the drug and information on the ratio of diseased leaves.

In the information collection unit 100, the pathogen scattering determination unit 200, the additional drug distribution determination unit 300, the pathogen infection determination unit 400, and the additional drug distribution determination unit 300, which will be described later, transmit necessary information to each. can

At this time, in the information collection unit 100, information necessary for the pathogen scattering determination unit 200, the additional drug distribution determination unit 300, the pathogen infection determination unit 400, and the additional drug distribution determination unit 300 is input. The order and the order of transmitting information to each component are not limited to a specific order. For example, although application information closest to the current time of the drug may be entered in advance in the information collection unit 100, it is not limited thereto, and at the request of the additional drug application determination unit 300 to be described below, the current time and the closest distribution information may be input. After the proximity spray information is input, it may be transmitted to the additional drug spray determination unit 300 .

The information collection unit 100 transmits weather information to the pathogen scattering determination unit 200 .

The pathogen scattering determination unit 200 determines whether or not the pathogen scatters by a predetermined method based on weather information transmitted from the information collection unit 100 . The scattering of pathogens proves that there is an activity possibility of the pathogen, and the pathogen scattering determining unit 200 may determine the maturity of the pathogen and determine whether or not the pathogen is infected.

The pathogen scattering determining unit 200 determines whether crops are infected with pathogens, and transmits pathogen scattering information to the additional drug spraying determining unit 300 or the pathogen infection determining unit 400 to be described later.

When pathogen scattering information including the possibility of pathogen scattering is transmitted from the above-described pathogen scattering determining unit 200, the additional drug distribution determining unit 300 determines one or more of precipitation information before the current time and precipitation information after the current time. It is determined whether or not to additionally spray the drug on crops using

The additional drug spray determination unit 300 may generate additional spray information determined to spray the drug until the expected precipitation time, which is before rain, by using precipitation information before the current time. In addition, the additional drug spray determination unit 300 determines whether the pathogen infection determination unit 400 to be described later uses the precipitation information after the current time, and then receives the pathogen infection information to determine whether the pathogen infection occurs. Depending on each step, it is possible to generate additional spraying information determined to spray the drug. A detailed description of this will be given later.

The additional drug application determination unit 300 transmits the generated additional application information to the application unit 500 .

The pathogen infection determination unit 400 generates pathogen infection information and transmits the generated pathogen infection information to the additional drug distribution determination unit 300 .

At this time, the pathogen infection determining unit 400 determines whether or not the pathogen is infected using weather information including relative humidity and temperature and diseased leaf ratio information. A detailed description of this will be given later.

The spraying unit 500 receives additional spraying information from the additional spraying determination unit 300 of the drug, and sprays the crops with the drug based on the additional spraying information.

Referring to FIG. 2, a process in which the pathogen scattering determination unit 200 determines whether or not the pathogen scatters in crops will be described.

The pathogen scattering determination unit 200 may determine whether or not the pathogen scatters by using a model formula.

The pathogen scattering determination unit 200 checks a daily average temperature from a predetermined date to the current date from weather information.

The pathogen scattering determination unit 200 generates summed temperature information by summing the average temperatures of days when the daily average temperature is zero from a preset date to the current date using the current date among the time information.

At this time, the preset date means December 1 of the previous year, but is not limited thereto.

The pathogen scattering determination unit 200 takes the calculated total temperature information as the x value, inputs it into Equation 4 below, and calculates the y value, the ascospore maturity value.

y = 116.29/(1+e^((941.44-x)/232.60)) - 1.33 <Equation 4>

At this time, Equation 4 is an equation determined to calculate the maturity value of ascospores based on pear trees, but is not limited thereto.

If the ascospore maturity value, which is the y value calculated in Equation 4, exceeds 0 and is less than or equal to the predetermined ascospore maturity value, the pathogen scattering determination unit 200 determines that there is a possibility of pathogen scattering, and determines that there is a need for today's control.

In addition, the pathogen scattering determination unit 200 determines that there is no possibility of pathogen scattering when the ascospore maturity value, which is the y value calculated in Equation 4, exceeds the preset ascospore maturity value, and determines that there is no need for today's control.

If it is determined that there is no possibility of pathogen scattering in the pathogen scattering determination unit 200, the control method according to the present invention ends in this step.

In addition, even if the ascospore maturity value, which is the y value calculated by the pathogen scattering determination unit 200 in Equation 4, is less than 0 or exceeds the preset ascospore maturity value, the crop's growth stage is germination or higher, or the crop has an asylum If it is confirmed that there are spores, it is determined that there is a possibility of pathogen scattering.

That is, although the pathogen scattering determination unit 200 uses the above-mentioned formula 4, which is a predicted value based on meteorological information, the pathogen scattering determination unit 200 considers the actual measurement of the pathogen maturity of the crop and the growth state of the crop. Thus, the possibility of pathogen scattering can be determined.

Accordingly, in the present invention, the possibility of pathogen scattering of crops can be determined by considering both predicted values and actual values through the model formula.

At this time, the researcher can determine the possibility of pathogen scattering by checking the growth state of the crop and inputting the input to the pathogen scattering determination unit 200, but is not limited thereto, and this process is performed without input from the researcher. may proceed.

At this time, the germination period may mean that the growth stage of the pear tree is higher than the germination period (Nun07, Hwachong 53).

At this time, the preset ascospore maturity value means 99, but is not limited thereto.

The pathogen scattering determination unit 200 transmits pathogen scattering information including whether there is a possibility of pathogen scattering and no possibility of pathogen scattering in the crop to the additional drug spreading determination unit 300 to be described later.

When the pathogen scattering information transmitted from the pathogen scattering determining unit 200 includes the possibility of pathogen scattering, the additional drug distribution determination unit 300 determines one or more of precipitation information before the current time and precipitation information after the current time. It is used to determine whether additional spraying of the drug is necessary for crops.

Referring to FIGS. 3 and 4 , a method of determining whether additional spraying of a drug is necessary for crops using precipitation information after the current time will be described.

The additional drug spray determination unit 300 uses whether precipitation is predicted within 6 hours from the current time and the effective expiration time of the sprayed drug closest to the current time, and finally determines the drug effect until the predicted precipitation time after the current time. It will produce additional dispensing information considering situations outside the expiration time.

When the pathogen scattering information is transmitted, the additional drug distribution determining unit 300 determines a preset drug efficacy maintenance date based on the current date.

If the current date is April, the preset drug effect maintenance date is determined to be 7 days, and if the current date is any one of May, June, October, and November, the preset drug effect maintenance date is determined to be 10 days.

In the present invention, it is assumed that the current date is any one of April to November, and from the current date, December to March, which is a period in which pathogens do not actively move, will be excluded and explained due to the nature of pear trees.

The additional drug application determination unit 300 receives application information from the information collection unit 100 and determines the expiration time calculated by summing up the effective maintenance date from the application time closest to the current time included in the application information.

For example, if the current date is April 10, and the spraying time is April 6th at 11:03, the expiration time is April 13th at 11:00, which is the sum of the spraying time and 7 days, which is the preset effective maintenance date. 3 minutes.

At this time, the spraying information includes information about the spraying time closest to the current time and the type of sprayed drug at that time.

The additional drug application determination unit 300 determines whether the predicted time of precipitation included in the meteorological information is before the expiration time of the medicinal effect.

If the precipitation prediction time is before the drug expiration time, the additional drug spraying determination unit 300 determines any one of a plurality of spraying mechanisms preset for crops from the current time to the control deadline according to the total amount of precipitation. Additional spraying information determined to spray the drug according to the spraying mechanism is generated, and the generated additional spraying information is transmitted to the spraying unit 500 .

At this time, the control time limit means that it is before a predetermined time from the precipitation expected time, and the additional drug spray determination unit 300 sets a time point 6 hours before the precipitation expected time as the control time limit.

At this time, the total amount of precipitation means the sum of the amount of precipitation for each hour from the current time to the expiration time of the medicinal effect.

In addition, the additional drug spray determination unit 300 determines that additional spray of the drug according to this step is not necessary if the expected precipitation time is not before the drug effect expiration time.

The additional drug application determination unit 300 calculates the total amount of precipitation by summing up the amount of precipitation for each hour from the current time to the time when the medicinal effect expires.

The additional drug spray determination unit 300 determines whether the calculated total precipitation is 30 mm or more, and if the total precipitation is 30 mm or more, it is determined to spray the drug according to the fourth spraying mechanism until the control time limit.

At this time, the fourth spreading mechanism may mean a spreading mechanism (c).

The drug additional spray determination unit 300 determines whether the calculated total precipitation is 30 mm or more, and if the total precipitation is less than 30 mm, it is determined to spray the drug according to the fifth spray mechanism until the time limit for control.

At this time, the fifth spreading mechanism may mean a spreading mechanism (Ka).

Referring to FIGS. 5 and 6 , it will be described that the additional drug application determination unit 300 determines whether additional drug application is necessary for crops using precipitation information prior to the current time.

When pathogen scattering information is transmitted, including the possibility of pathogen scattering, the additional drug distribution determining unit 300 determines whether or not the crop is infected with the pathogen.

The pathogen infection determination unit 400 checks the current time when rain started immediately before the current time and the nearest precipitation time from the meteorological information.

At this time, the pathogen infection determination unit 400 may check the time when it rained before the current time in units of time, but is not limited thereto. For example, if the time of precipitation is from 23:00 to 6:00, the time of precipitation closest to the current time is set to 6:00.

At this time, if the rain stopped and returned within 6 hours, it is judged that the rain came continuously.

The pathogen infection determination unit 400 determines whether the precipitation time is after the spraying time.

The pathogen infection determination unit 400 determines whether the residual efficacy is 0 or more when the precipitation time is after the spraying time.

The pathogen infection determination unit 400 determines that the remaining drug efficacy is 0 mm if the current time is not before the drug expiration time.

In addition, the pathogen infection determination unit 400 determines the remaining drug efficacy from the application information when the current time is before the drug efficacy expiration time.

The residual medicinal effect is calculated by subtracting the amount of precipitation every hour from the spraying time closest to the current time to the current time from the value determined according to the spraying information and the diseased leaf ratio information.

In this step, the additional drug spray determination unit 300 may determine the control agent input level based on the total amount of precipitation expected for selection of additional control agents in addition to the control time limit. That is, the additional drug spray determination unit 300 may control by selecting intensive control and extensive control.

The value determined according to the spraying information and the diseased leaf ratio information is 25mm for the diseased leaf ratio of less than 1% and 15mm for the diseased leaf ratio of 1% or more when the drug is sprayed according to the 5th spraying mechanism, and if the drug is sprayed according to the 4th spraying mechanism It may be 100 mm, but is not limited thereto.

At this time, the fourth spreading mechanism is a spreading mechanism (C), and the fifth spreading mechanism means a spreading mechanism (Ka), but is not limited thereto.

The pathogen infection determination unit 400 sets the depletion time when the remaining drug efficacy becomes zero.
